This morning I attended the Panasonic IP Camera Seminar at Panasonic Malaysia in Shah Alam. The drive was smooth but I was lost in Shah Alam trying to locate the place. I did not bring along my GPS but I managed to get to USJ11 where I was a little more familiar with. I took the long way by getting to the Federal Highway, paid the toll and found Panasonic Malaysia at last.

The seminar was organized by Panasonic and its distributor. Not so much of interesting talk. Organization was a little messy but overall good. Speakers were not very well trained and lack of exposure. The entire presentation was not too bad at all and it wasn’t boring as there were some people asking interesting questions. Most important of all was that I managed to establish contacts with Panasonic Malaysia.

Panasonic treated its guest very well with a nice buffet lunch. I took the lunch, washed down with dessert and drinks. Talked to my vendor and to establish closer relationship.

Then I had to rush to Hilton PJ to attend another IP camera event. It was a dealers gathering organized by Axis Communication and one of its distributor in Malaysia. The event was organized in Uncle’s Chili, a restaurant pub. Nice setup and cozy environment. The presentation was presented by Axis Singapore. The presentation was absolutely good and informative. Axis is a Swedish company and its IP cameras are world number 1.

Axis presentation had been very entertaining and educating at the same time. The presenter, Nafis Jasmani, had done a great job.

Axis and its distributor treated their guests very well too. Excellent and delicious food. I had a great “meal” with a beer together with some people I met there. Dessert was great too! The only thing I disliked was that people began to puff cigarette after food and beer. The smoke immediately destroyed the cozy environment and the nice cool air.

I spoke to Nafis before I left. We talked about Axis Developer Program and some technical details. As I understood from him, there are 4 developers in Malaysia developing some vertical Axis solutions. Quite an interesting fact.

Steganography and Information Security

December 11th, 2007 at 18:19 · Filed Under Call Me a Geek, Hacking, Information Forensics, Technology, Web · Comment 

One of the major threats in this information age is the exposure of sensitive information in the Internet. The most common method of securing information is through encryption technology. Today, 128-bit technology is the commonly used encryption method in emails and documents. Recent upheaval as my ISP closing down port 25 for SMTP (Simple Mail Transfer Protocol) has rung an alarm to my computing needs on the Internet. My ISP’s decision is to curb spammers who have abused direct SMTP access to email servers. The act is a foolish one as this will not stop spams but at the same time, it affects those genuine users.

A 128-bit encryption can be broken into with cluster computer. A cluster computer consists of computers, called nodes, with one or more CPU. These computers are connected to a network. A special program capable of distributing calculation tasks to all the nodes is needed. This architecture is called Beowulf. Breaking a 128-bit encryption is just a matter of time depending on the number of nodes and the number of CPUs on each node.

My ISP forces all direct SMTP connection to be routed to an unsecured proxy server. As an emergency contingency to my Internet use, I quickly setup encryption for my email client. So far, the closing of port 25 has not affected me.

As I have the need to send sensitive work information across the Net, I feel the encryption is not enough on a unsecured proxy server. I would elevate the level of information security by using steganography together with encryption.

Steganography is a technique to embed information to a digital photo or picture without altering the photo or picture at eye level. The technique uses advanced algorithm to manipulate bits of data in the digital image with the bits from the information I am going to send. To extract the information from the encrypted digital image, an original image is the key. Only my intended recipient has an original copy of the digital image.
