Abstract: An information push method comprises: receiving a distance parameter reported by a client terminal; determining whether a distance to the client terminal satisfies a preset distance condition according to the distance parameter; and when the distance to the terminal satisfies any preset distance condition locally, pushing information corresponding to the preset distance condition to the client terminal, wherein different distance conditions correspond to different information locally and respectively. The techniques of the present disclosure respectively push different information to a user based on different distances to client terminals, and adapt to different user application scenarios, thereby improving the user experience.

Abstract: Methods and devices of authentication via user behavior for use in a mobile device. The method may include initiating an authentication via user behavior for an application transaction process and suspending the application transaction process before the authentication is successful; acquiring the latest radio frame from a beacon and determining a distance parameter based on the radio frame after the authentication is initialized; determining whether a specified distance condition is satisfied for the beacon and the mobile device; and in response to a determination that the specified distance condition is satisfied for the beacon and the mobile device, determining that the authentication is successful and resuming the application transaction process that was suspended previously.

Abstract: Example positioning techniques include: generating an initial particle set, randomly allocating different moving step lengths for each particle in the initial particle set, updating position information of each particle at a previous moment to obtain a current particle set, rating usability of each particle according to position information of each particle in the current particle set and a signal fingerprint received at a current moment, acquiring a moving step length of each particle having a rating higher than a first predetermined threshold in the current particle set, and updating a moving step length of each particle having a rating lower than the first predetermined threshold according to the acquired moving step length. The techniques of the present disclosure obtain a moving step length closest to the actual step length of a person, and update the moving step length in time with the change of the step length of the person.

Abstract: The present disclosure introduces a method and an apparatus of automatic information placement. A server receives display location publishing information and determines a value index of a corresponding display location according to the received display location publishing information. When the server receives an information placement request, the server determines an investment index of corresponding placement information according to the received information placement request. The server compares one or more value indexes of display locations with one or more investment indexes of one or more placement information, and places respective placement information at a corresponding display location according to a comparison result. The present techniques improve the efficiency of placing information and optimizing resource deployment.
