Although GSM's architecture is designed in such a way to provide various security features like authentication, data/ signaling confidentiality, and secrecy of a user yet the GSM channel is susceptible to replay, interleaving and man-in-the-middle attacks. The GSM speech service is secure up to the point where speech enters the core network. However to achieve end-to-end security it is desired that the GSM subscriber, not the network operator controls the encryption on the speech channel. A new approach of encryption at the user-end is introduced. In this paper we have tested our encryption technique on the GSM communication system using TMS320C6713 DSP Starter Kit (DSK), in real-time. Our technique encrypts the speech before entering the GSM handset which adds security and privacy. The encryption algorithm being private to the communicating GSM subscribers, the GSM channel will become exclusively confidential for them. The DSK board was used as a separate module of the system implementing the encryption algorithm. Real-time experiments were conducted to check the performance of the system in terms of its performance and latency rate.","PeriodicalId":307661,"journal":{"name":"2009 International Conference on Emerging Technologies","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121720855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we have introduced a new approach for the depth estimation problem of a visual control system with a moving camera and stationary target. A unique visual pattern is designed to achieve the desired depth of the vision based system. In this paper the unknown depths of the special geometrical feature points are estimated from the pre-calculated depth calibrated equations, whose affects are then combined to acquire the desired goal. This specialized technique doesn't require any conventional camera calibration parameters, e.g., camera intrinsic parameters; rather it works on the specialized and accurate depth calculating calibration equations described in this paper. Simulation and experimental applications are presented which verify the performance of the proposed technique. The vision system, i.e., a wireless camera, pointing downwards, is mounted with a mechanical assembly which can move laterally as well as up and down. The required algorithm is designed in MATLAB which is capable of reading real-time images and processing it for proper lateral position and desired depths calculation at particular instants.","PeriodicalId":307661,"journal":{"name":"2009 International Conference on Emerging Technologies","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122277462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
