Authentication method and system for CAPTCHA Turing test based on static characters
InactiveCN103093138AIncrease the difficultyStrong defenseDigital data authenticationString databaseSemantics
The invention discloses an authentication method and a system for CAPTCHA Turing test based on static characters. The authentication method and the system for the CAPTCHA Turing test based on the static characters include the following steps of establishing a communication connection between a server and a client, selecting randomly a static string in a static string database stored the server in advance, segmenting the static string into single characters, then calling a character image to generate a function which converts single characters into image representation, placing the single characters represented by the image into a region formed by a circular or elliptic boundary to show as a verification code on the client so as to carry out the Turing test CAPTCHA. Utilizing the region formed by the circular or elliptic boundary to place the verification code, the method can effectively prevent the character from being segmented by conventional pixel segmentation, and thus increases the difficulty of attack. The method carries out distortion, mirror image, and increasing interference lines for characters. The method carries out the characters arrangement according to the specific semantics of the characters and increases more human participation and can guarantee the safe man-machine interaction.

Method of designing watermark in consideration of wiener attack and whitening filtered detection
InactiveUS7076081B2Easy to detectEliminate the problemUser identity/authority verificationCharacter and pattern recognitionHypothesisEngineering
Disclosed a method of designing a watermark having the power spectral density optimized so that the detection performance can be improved by employing the whitening filtered detection after the Wiener attack. The power spectral density of the watermark is designed using an optimization method that can improve the entire detection performance by reflecting the gain of the whitening filter after the Wiener attack. A higher detection gain is obtained using the whitening filter after the Wiener attack, and the expected value of the difference between test statistics of the two hypotheses that the watermark exists and the watermark does not exist, respectively, is maximized to optimize the detection performance. Regarding the expected value of the difference between the test statistics as an objective function, the power spectral density of the watermark, which corresponds to a maximum differentiated value of the power spectral density of the watermark using the Lagrange multiplier method, is obtained.
