The design and implementation of Flash animation watermarking

In view of the problems that exist in the copyright protection of Flash, a kind of digital watermark design scheme based on Flash animation is proposed. This scheme chooses the grey scale images including the more copyright information as the watermark information, and inserted them into the SWF files that are read in the byte array. The experiment demonstrates that, while it does not influence the playing result, this scheme can ensure the invisibility, high hiding capacity, etc. that are characteristic of the watermark, and can resist the decompilation attack effectively.
