发明名称 Method and device for protecting stored data
摘要 Generic information storage devices (magnetic, optical, biological/organic devices) are well-suited for storing, processing, archiving or transporting large amounts of information; they can, however, only be secured against unauthorized access using cryptographic methods. Undetected physical copying and manipulation of the information remains, however, possible. Disclosed is a process and device for combining non-intelligent generic information storage devices with intelligent storage devices and linking their information. The process compresses the stored data from a generic storage device and counts a signature count of the stored data. An ID is then provided to the stored data from a permanently assigned intelligent programmable memory chip. At least part of the compressed data is encrypted using an asymmetric key and transferred to a memory area of the permanently assigned intelligent programmable memory chip.
