Becoming Teachers, Becoming Researchers: a Case Study
This paper presents a case study of a group in initial primary teacher education students becoming researchers of their peers’ course experiences of school – university links. The connection between university teacher preparation programmes and work in school is a well-researched area with suggestions that there is a marked disconnect between the two. The project took an emergent approach to le...
متن کاملRandomised Dynamic Traitor Tracing
Dynamic traitor tracing schemes are used to trace the source of piracy in broadcast environments such as cable TV. Dynamic schemes divide content into a series of watermarked segments that are then broadcast. The broadcast provider can adapt the watermarks according to the pirate’s response and eventually trace him/her. As dynamic algorithms are deterministic, for a given set of inputs, the tra...
متن کاملA Fully Public-Key Traitor-Tracing Scheme
We propose a fully public-key traitor-tracing scheme in which each subscriber can choose his or her own private decryption key without others learning the key. The distributor of the digital content utilizes the public data coming from all subscribers to compute a public encryption key. The paid contents are then transmitted to the subscribers, after being encrypted with the public key. Each su...
متن کاملAn Attack on A Traitor Tracing Scheme
In Crypto’99, Boneh and Franklin proposed a public key traitor tracing scheme [1], which was believed to be able to catch all traitors while not accusing any innocent users (i.e., full-tracing and errorfree). Assuming that Decision Diffie-Hellman problem is unsolvable in Gq, Boneh and Franklin proved that a decoder cannot distinguish valid ciphertexts from invalid ones that are used for tracing...
متن کاملThreshold Traitor Tracing
This work presents threshold tracing schemes. Tracing schemes trace the source of keys which are used in pirate decoders for sensitive or proprietary data (such as pay-TV programs). Previous tracing schemes were designed to operate against any decoder which decrypts with a nonnegligible success probability. We introduce threshold tracing schemes which are only designed to trace the source of ke...
