A compression tool can provide security to some degree, if the algorithm itself is kept secret. Whenever the algorithm is known, as is the case for conventional compression, we can not expect secrecy out of the tool. If security is needed as well, compression can be combined with encryption. To employ a system that would afford security while compressing, a novel technique (named as secure compression -SeCom) has been designed and implemented. We present the experimental results obtained by applying this scheme on texts from English and Turkish corpora. The results are promising in terms of compression quality and throughput, measured in bpc and MB/min, respectively.
