Architecture of web-mashup, which consists of the three parts has been described. The process of the creation the mashup-service on data level, on process level and on presentation level has been presented. Four specific search strategies that use different kinds of information for query ranking and selection have been proposed.Item Authenticity of digital images(Видавництво Львівської політехніки, 2013) Hanzlik, Lucjan; Wodo, WojciechCopyrights are a big issue these days, it is extremely easy to loose our intellectual property (in sense of digital images) and thus money, moreover it is hard to proof our rights in the court. Our digital pictures must be protected in such a manner that it should be easy to proof we are the legitimate owner of the image and it should be computationally hard to forge such proof. We present a sketch of a new solution for copyright protection of digital images using chameleon hash functions, signatures and steganography. It is an extension of previous work in this field. We introduce a probabilistic similarity method into our scheme, which convince the verifier at certain level about the owner of the picture.Item Automatic paralleling of tasks in reconfigurable multiprocessor systems(Видавництво Львівської політехніки, 2013) Zhabin, Valeriy; Liashchun, ІhorA method of automatic paralleling of tasks that accelerates computing in reconfigurable multiprocessors systems based on the dataflow model is given.Item Basic operations of modern hashing algorithms(Видавництво Львівської політехніки, 2013) Melnyk, Viktor A.; Kit, Andriy Y.In this paper we performed a comparative analysis of hashing algorithms SHA-1, SHA-2, MD-5, RIPEMD, Keccak respecting a set of their basic operations.
