A Chaotic-Based Digital Watermarking Algorithm for Tag Tamper Detection

RFID tags has been used more widely, but the tag information is easy to be tampered, so its tampering detection has become a focus in order to ensure information security. An improved digital watermarking algorithm based on chaotic tent mapping has been proposed. In the improved algorithm, integer piecewise linear chaotic tent mapping has been used to improve the watermarking generating and embedding, and enhance the safety and efficiency of the algorithm, at the same time the simultaneous detection of EPC Manager and Object Class segments have been achieved. The proposed solution algorithm conforms to the EPC-Class1 Generation2 specification.
