    摘要： A probability of an observation sequence stored at a client is evaluated securely with respect to a hidden Markov model (HMM) stored at a server. The server determines, for each state of the HMM, an encryption of a log-probability of a current element of the observation sequence. Determines, for each state of the HMM, an encryption of a log-summation of a product of a likelihood of the observation sequence based on a previous element of the observation sequence and a transition probability to the state of the HMM. Determines an encryption of a log-likelihood of the observation sequence for each state as a product of the encryption of a log-summation and an encryption of a corresponding log-probability of the current element of the observation sequence; and determines an encryption of the log-probability of the observation sequence based on the log-likelihood of the observation sequence for each state.

    摘要： A method for implementing switching when the network is faulted is disclosed, and the method includes: establishing a quick detection mechanism between non-querier and querier; the non-querier using the detection mechanism for performing a real-time detection on the querier and downlink of the querier; switching the non-querier to be the querier when the non-querier detects that the querier or the downlink of the querier is faulted. A querier is further disclosed. With the method, it can complete a quick switching of the querier and a quick transmission of a multicast flow when the querier or the downlink thereof is faulted, thereby reducing the interrupt time of users receiving the multicast flow, implementing a quick protection of a multicast service, and improving the service experience for the user.
