متن کاملGood traceability codes do exist
Traceability codes are combinatorial objects introduced by Chor, Fiat and Naor in 1994 to be used to trace the origin of digital content in traitor tracing schemes. Let F be an alphabet set of size q and n be a positive integer. A t-traceability code is a code C ⊆ Fn which can be used to catch at least one colluder from a collusion of at most t traitors. It has been shown that t-traceability co...
متن کاملObtaining Traceability Codes from Chinese Reminder Theorem Codes
SUMMARY Traceability codes are used in schemes that prevent illegal redistribution of digital content. In this Letter, we use Chinese Reminder Theorem codes to construct traceability codes. Both the code parameters and the traitor identification process take into account the non-uniformity of the alphabet of Chinese Reminder Theorem codes. Moreover it is shown that the identification process ca...
متن کاملOn a Class of Traceability Codes
Traceability codes are designed to be used in schemes that protect copyrighted digital data against piracy. The main aim of this paper is to give an answer to a Staddon-Stinson-Wei’s problem of the existence of traceability codes with q < w and b > q. We provide a large class of these codes constructed by using a new general construction method for q-ary codes.
متن کاملCombinatorial properties of frameproof and traceability codes
In order to protect copyrighted material, codes may be embedded in the content or codes may be associated with the keys used to recover the content. Codes can ooer protection by providing some form of traceability for pirated data. Several researchers have studied diierent notions of traceability and related concepts in recent years. \Strong" versions of traceability allow at least one member o...
