Abstract(in English) | A secret sharing is attracting attention as an algorithm in cryptography. It is a method in which the source data is divided into n pieces and the source data is reconstructed from any k pieces but no knowledge of the source data is not revealed from k-1 pieces. This algorithm is called (k, n) threshold scheme. In this study, we propose a method, in which the source data is divided into n secret sharing data in the first step and each shared data is compressed in the second step. The necessity of compression depends on the conditions, then this scheme has a merit such that whether the data is compressed or not is selected after protecting the data. The compression adopts a method used in distributed video coding based on error correction codes. Assuming the ideal error correction decoding, any k shares reconstruct the source data. On the other hand, assuming the non-ideal error correction, the reconstruction quality is degraded. In such a case, using k+1 shares enhances the quality. Computer simulations show the validity of the proposed scheme. |
