At the time of his arrest, Dmitry Sklyarov was a 27-year-old Russian citizen, Ph.D. student, cryptographer and father of two small children (a 2-1/2 year old son, and a 3-month-old daughter).
Dmitry helped create the Advanced eBook Processor (AEBPR) software for his Russian employer Elcomsoft. According to the company's website, the software permits eBook owners to translate from Adobe's secure eBook format into the more common Portable Document Format (PDF). The software only works on legitimately purchased eBooks. It has been used by blind people to read otherwise-inaccessible PDF user's manuals, and by people who want to move an eBook from one computer to another (just like anyone can move a music CD from the home player to a portable or car).
Dmitry was arrested July 17, 2001 in Las Vegas, NV, at the behest of Adobe Systems, according to the DOJ complaint, and charged with distributing a product designed to circumvent copyright protection measures (the AEBPR). He was eventually released on $50,000 bail and restricted to California. In December 2001, was permitted to return home to Russia with his family. Charges have not been dropped, and he remains subject to prosecution in the US.
Although Dmitry is home now, the case against Elcomsoft is continuing (to the detriment of the company), Dmitry's actions in Russia are controlled by a US court, and DMCA is still the law (to the detriment of everyone). This site will carry updates as they come...
