Interesting Information About Spam

Spam is the colloquial term for junk or unsolicited email, and we all get way too much of it. It is also, arguably, the most prevalent form of Internet crime. I say arguably because the CAN-SPAM Act of 2003 legitimatized many different forms of email spam, but in January 2004 less than 1% of email spam complied with the CAN-SPAM Act.

I currently have 208 messages in my spam folder, and spam more than 30 days old is deleted, which means that I'm getting an average of 7 spam messages a day this month. Knowing that there is just so much of it made me curious as to what type of spam there is, what methods spammers use to try and dodge email filters and what has changed in regards to spam over time, and if I'm interested in this I'll bet someone else is too. So sit back and read all about the email that everyone loves to hate, spam.

Interesting Spam Statistics

14.5 billion spam messages a day are sent, and 45% of those are considered spam. Some estimates even put that percentage as high as 73%.

The vast majority of that obscene number of spam emails can be classified as pharmaceuticals. These emails promise the recipient everything from better skin or effortless weight loss to improved sexual prowess. These, along with a slew of replica watches and online casino ad's, makes up almost the entirety of your spam content.

Phishing and Scamming Spam
Only 0.67% of spam is a scam or a phishing attempt, but that portion is a dangerous one. Phishing works, that's why people create these scams. One of the more recent and effective phishing scams was the email from "E-Bay" telling you about the "charge to your account".

Clicking on anything in the email will immediately download a virus onto your computer, and quite a few people click without thinking when they feel like their money is on the line. Scammers know that, which means it is essential that you keep your guard up whenever you receive a suspicious email, because as internet filtration improves so do the scammers.

A Choice Spam Filtration Avoidance Technique

Image spam, as you can see in the above graph which is current to the week of my blog post, is a highly active but thankfully still fairly small portion of overall spam. Image spam is a method wherein the spam content is displayed as an image file rather than text. This is to prevent the effectiveness of text based filtration. This is interesting because as filtration improves so do the advances in image spam. There are some ad's that contain an animated image with the starting frame containing no text so that even through image analysis the spam cannot be sorted.

Fun With Spam

So, spam is complex and ofttimes dangerous, but mostly just damn annoying. There isn't much we can do about it though, spam is here to stay, so we might as well just get all the enjoyment and spamusement we can out of it.

RFID Tags

RFID Tags, A Crash Course
RFID tags are coming up more and more in conversation these days, but until now I could honestly say that I had only the vaguest idea of how they work and what the actual privacy risks of RFID technology were, which is surprising since I've been in a fair number of privacy debates about them. I hope to both solidify my knowledge and rectify this for anyone who has found themselves in the same situation I was with this blog post.

So, what the heck is RFID?

Lets start off this little crash course in RFID technology by attaching some words to that acronym. RFID stands for Radio-Frequency IDentification. This is a very useful thing to know, because it also introduces the main concept behind RFID tags as a whole: Radio Waves. In the simplest terms, and really that is the best way to describe anything, RFID is a method of transmitting data about an object (animate or inanimate) using a unique serial number over radio waves. This is arguably better than bar-code technology because there is no need to see or even be relatively close to the RFID tag in order to read it.

What are the components of an RFID system?
I'm glad you asked! Rather than give you a big old boring description, just take a look at this picture. I've linked to the article it is from, but the picture was the only thing I looked at until my second pass through my relevant information on RFID tags.









What are the different types of RFID tags?

There are both active and passive RFID Tags, as well as a hybrid of the two, just to make things complicated. Active RFID has an internal power source (most likely a battery) that allows the RFID tag to both receive and generate signals to and from the RFID reader. Passive RFID tags reflect energy from the RFID reader and use that to push out a low energy response. In my opinion just knowing that there is a hybrid RFID tag will most likely put you far ahead of anyone you are discussing this with, and you can probably extrapolate why it is different from the name, but you can read more here if you want.




















Where would I encounter RFID technology?
It is quite possible that the information I give you on this will be aged by the time you read it, so I'll be vague in my description of potential uses of RFID so as not to age my blog prematurely, but the main use of RFID tags is tracking either a product or a person. You will find that all my examples are just building off of this core use:
  • Manufacturing (Tracking work in progress)
  • Retailing (Tracking merchandise, both shipping and theft prevention)
  • Toll roads (Tracking cars and payments incurred)
  • Security and access control (Tracking where people can and should be)
Now imagine if RFID tags were used for products you can purchase at, say, Wal-Mart, as is referenced in the following article. You would simply pick out what you want and leave, and the items would be automatically recorded and charged to your RFID enabled credit card. This would mean the death of the line, the beginning of the end of standing around waiting for the store to get around to taking your money.

Last potential scenario: Imagine being able to automatically set your Tim Horton's order before you get to the drive-thru, maybe using your RFID enabled smart phone. You just drive up, no waiting, and grab your order. Once you have it in hand your credit card is automatically charged. No fumbling in your cup holder for that quarter you know you put there, no awkward shifting to reach your wallet in your pocket, no hassle at all.


What's all this about privacy concerns?
Since RFID is designed to be tracked, privacy automatically becomes a major concern, in many cases with good reason. I will propose to you some scenarios, but I leave it to you to make your own conclusions, since I'm not even sure how I feel about it all yet.

If everything you buy has an RFID tag in it, let's say to prevent theft, who is to say that they stop being used when you purchase the item? Anonymity can be easily lost if many of your belongings have an individual identification number. Would this information be accessible to the police? The government? Would it be possible to put in a court order for records of the location of your belongings at a specific time?

Also, who is to say that you know about having an RFID tag on you at all? The technology has advanced to the point that RFID tags are so small as to be practically invisible, as they are comparable to a grain of sand in some cases. This opens the flood gates to being tracked against your will or knowledge by pretty much anyone with access to an RFID reader and tag.

Finally, remember the potential scenario suggested above; if your credit card information is flying through the air on radio waves how long would it be before someone learns how to take advantage of that?

Where can I go to read more?
If you wish to check your facts, which I highly recommend in general, you can take a look at How Stuff Works, which has an excellent and detailed article on RFID tags.

Another excellent stop in your quest for knowledge would be the Association for Automatic Identification and Mobility. They also have an almost too extensive glossary which you might enjoy.

To read more about privacy issues you can take a look at this article from CNet News.

Remember to keep sharp and don't forget that everyone has a bias. Find your facts through a variety of sources and develop your own opinions.

Internet Privacy

Internet privacy is a really complicated issue, and honestly I'm not sure how I feel about it. I googled myself, and managed to learn rather a lot about me just on the first page of results. Now, I honestly can't say whether this upsets me. I'm offended that the facebook person shown isn't actually me, but I can assume that I would be bothered as well if my facebook page came up when I was googled, as is evidenced by my strict privacy settings on facebook. This signifies to me a weird dichotomy between wanting to be known and wanting to protect my privacy.

In mere moments you can find that I am a member of two campus organizations, that I have a Twitter account, one of my recent classes, and that I got a bursary to attend a computing conference. I feel that I don't have the right to be upset by any of this, but at the same time I worry over how this information can be used to learn far more than I want to be easily available.

To test how far I can get with this I visited the websites of both organizations, as well as my Twitter page. From there you are able to learn about my participation in another conference and are able to make reasonable guesses on a wide variety of people that I most likely know, especially by putting this information together with the general blurb that I place mostly everywhere, stating the University I attend. Because of all this I believe that it would be fairly easy to track me down. "Knowing" some of my friends would probably get me to talk to you, at least up until now when I started worrying about this.

I can be sure that that does bother me, since I went back and generalized all of the above information when my over-active imagination got me thinking about all the damage this could cause.

So what is more important? Where is the happy medium in all this? According to so many resources, but for this quote specifically ArticlesBase:
"Today, many human resource department's search the internet for profiles, photos and other information, good or bad, to learn about and judge prospective new employees. "
So having some information online is potentially very useful, especially in a technological job market. But with an online world of blogs , Twitter, Facebook and all sorts of things that make the Internet fun, having an online presence is a slippery slope of interconnected webs of information, helpfully collected and cross referenced so that you only need to be able to search to learn an awful lot about a person.

I still don't know how I feel about being so easily found online, all I know is that I'm walking away from this blog significantly more paranoid and nervous. I guess 'constant vigilance' is an excellent motto for being online at all, maybe that is too easy to forget now that the Internet is such a pervasive part of our lives.

Toronto Girl Geek Dinner - Tons of Fun

I just got back from an event called Toronto Girl Geek Dinners, it was held at The Pilot, on Cumberland in Toronto, and there was a panel discussion and tons of techy women there. I must say I enjoyed it immensely. I really feel empowered to work on my resume and online persona, and it has put me in a job searching mood. Since I'm a University student, and will be going on co-op in the winter, its probably a good idea for me to get myself in gear on the whole resume related thing. I've got lots to add to my resume to get it up to date. I've been intending to make up an online resume, but I am constantly putting it off. I think it would be a great thing to be able to have photos of my work up online so that potential employers can get a look at what I do, I never feel like a 2 page paper gets me across as well as I would like it to. As they say, a picture is worth a thousand words, so what would a website designed by myself with both written information and photographic documentation of my work say about me? I think a whole lot.

On a fun side note, I won a pen set from Microsoft, the sponsors of the event. They were also giving away a Zune. At Grace Hopper Celebration of Women in Computing '08 I won a Zune from Microsoft, which was amazing. All through the prize draw it was joked about how ironic it would be if I won a Zune again, the odds would be like one in a million. I was happy to win something, Microsoft if you keep sponsoring events I attend I'll end up with enough prizes to fill a pool!

Take a look, this is the Zune I won at Grace Hopper:












And here is my magnificent pen set:













They are styled to look like golf clubs, I think my favourite is the sand wedge, its got a solid weight to it.

Skittles Vodka

I'm in the process of making Skittles Vodka right now. I'm referring to this website for my instructions:
http://mixthatdrink.com/skittles-vodka-tutorial/
My boyfriend and I mixed 6 shots of the purple skittles stuff last night and will be filtering it as soon as I finish this post. Should hopefully be delicious. Provided it is we plan on buying some dollar store bottles to store the concoctions in so we can have the rainbow of flavours like the picture on the provided website. Note: The recipe called for a pound of skittles.. I bought a kilo of it. Ahaha.. Oh well more for me to eat. ^^;

Meeting Madness - STEGADON RAH!

Sitting in a computer science club meeting. I feel like I should have an idea or a theme about the stuff I want to be saying here. It’ll give me a good focus. But that doesn’t mean that I can’t post randomness to go along with it.

I recently got involved in Warhammer. I’ve begun my Lizardman army. Purchased a Salamander as my first ever model and am almost all done painting him up. I’ve been working on trying to find a nice colour theme to base my entire army off of. I can’t quite decide. I’ve been considering three real colour schemes. Purple with green detail, green with purple detail and orange with dark green detail. The Salamander is red to orange and yellow with grey black detail. Common, but I like it anyways and its really working out well for me. My dad has gotten really into it as well which I am very happy about. He is currently getting a Vampire Count army and was nice enough to buy me a Stegadon and is happily building him for me. Its going to have the Engine of the Gods on it. Awesome.

Wordpress->Blogger?

I think I might be a deserter. I've just made a blog here and I already have one on wordpress.com
I guess I'll just use both until I decide which I like more, and let the other one drift off into the waves of the internet. I just made a post a minute ago, I'm going to move it on over here. Lets see if I like you Blogger.. prove yourself!
