Because biometrics-based authentication offers several advantages face to other authentication methods, it is important that such systems be designed to withstand attacks. Reliabil...
−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders at low error rates. Past experiments h...
In this paper, we introduce tamper detection techniques based on artifacts created by Color Filter Array (CFA) processing in most digital cameras. The techniques are based on comp...
