Kaspersky ups the ante in anti-spam battle
Anti-malware firm Kaspersky Lab has announced a new technology which it hopes will provide greater ammunition in the fight against spam.
The technology can detect text embedded in images without the need for machine recognition, which requires uniformity of size, style and arrangement of symbols in order to detect junk email. Spammers can avoid detection by distorting the images, explained Kaspersky Lab's senior technology consultant, David Emm.
The new technology, which has just been successfully patented in Russia, is based on probability and statistics. Images are filed as spam after an analysis of the layout of the graphic patterns of words and lines, or the content of the letters and words in those patterns, the company said.
