Provided is a method for providing an anonymous public key infrastructure (PKI) in a user terminal. The method includes receiving a real-name certificate from a real-name PKI service domain, requesting an anonymous certificate to an anonymous PKI service domain, and receiving the anonymous certificate from the anonymous PKI service domain. Accordingly, the method can ensure anonymity when a user uses a service by providing the anonymous certificate in association with the PKI-based real-name certificate.

A human tracking method using a color histogram is disclosed. The human tracking method using the color histogram according to the present invention can more adaptively perform human tracking using different target color histograms according to the human poses, instead of applying only one target color histogram to the tracking process of one person, such that the accuracy of human tracking can be increased. The human tracking method includes performing color space conversion of input video data; calculating a state equation of a particle based on the color-space conversion data; calculating the state equation, and calculating human pose-adaptive observation likelihood; resampling the particle using the observation likelihood, and estimating a state value of the human; and updating a target color histogram.
