This paper shows new algorithms and the implementations of image reorganization for EAN/QR barcodes in mobile phones. The mobile phone system used here consists of a camera, mobil...
Application of covering codes to data embedding improves embedding efficiency and security of steganographic schemes. In this paper, we describe several familes of covering codes c...
At PKC 2000, Inoue and Sakurai proposed some methods to design hash functions from block ciphers and codes (block codes and convolutional codes). They claimed that their hash func...
In this paper, we study the application of universal hashingto the construction of unconditionally secure authentication codes without secrecy. This idea is most useful when the nu...
We introduce a reliable memory system that can tolerate multiple transient errors in the memory words as well as transient errors in the encoder and decoder (corrector) circuitry....
