Abstract: A method and system for improving security of a mobile terminal can be used to determine whether the obtained slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner of the mobile terminal, thereby determine whether the current user is the owner, and perform corresponding processing. With this method and system, it is not required to remind a user to input verification information, such that the current user cannot perceive that verification is currently in process. Therefore, the validity of the verification can be ensured and the security of the mobile terminal can be improved effectively.

Abstract: A method and device for constructing an apk virus signature database and an apk virus detection system. The method comprises: obtaining a given sample set, the sample set being composed of N normal apk file samples and N virus-infected apk file samples; for any sample in the given sample set, separately obtaining M signature values of the sample according to M preset signatures; for any sample in the given sample set, separately obtaining M signature values of the sample according to M preset signatures; for any sample subset i (i=1, . . .

Abstract: Provided are a method, a device, a server, and a client device for video processing. The method includes: obtaining, according to the page address of a first video page, page source code of the first video page and video processing rules corresponding to the first video page, the first video page corresponding to the first video; obtaining from the page source code, according to the page source code of the first video page and the video processing rules corresponding to the first video page, video playback information of the first video. The method obtains, by using preset video processing rules, video playback information from a video playback page and associated with a video. Further, video can be played directly without entering a video playback page.

Abstract: Disclosed are an information pushing method and a client. The method is applied in the client, and the client collects use habit information of a user. The method comprises: detecting whether an information pushing trigger condition is satisfied, and if yes, obtaining current battery power information and current time information of the client; generating first prompt information matched with a current state of the user according to the usage habit information, the current battery power information and the current time information; and pushing the first prompt information.

Abstract: A first mobile device receives a request to send information updates from the first mobile device to the second mobile device, the request specifying a predefined geographical region. In response to the request, the first mobile device checks its current location and determines whether the current location is within the predefined geographical region. After determining that the current location of the first mobile device is within the predefined geographical region, the first mobile device sends a first information update to the second mobile device. Subsequently, the first mobile device sends a second information update to the second mobile device after determining that the current location of the first mobile device is outside the predefined geographical region.

Abstract: The present invention provides method and apparatus for power management of mobile devices and associated mobile devices. The method for power management of mobile devices includes acquiring a predefined battery power level variation ?n of the mobile device and its corresponding usage time t1 if the mobile device uses the power-saving functions; acquiring the same battery power level variation ?n of the mobile device and its corresponding usage time t2 if the mobile device does not use any power-saving function; and determining an extended usage time of the mobile device ?t=t1?t2, and notifying the user of the mobile device the extended usage time. By determining the extended usage time and notifying the user of the extended usage time, the user of the mobile device can have a better understanding of the usage state of the mobile device after adopting the power-saving functions and therefore an improved user experience.

Abstract: A method, an apparatus and a mobile device estimate remaining time required to fully charge a battery. The method may include (a) determining from one or more of the mobile device's charging records the time required for charging the battery of the mobile device by one unit of charge (“unit charging time”); and (b) based on the time so determined, calculating the remaining time required for fully charging the mobile device's battery. In this manner, an accurate estimate of the remaining charging time is achieved. In one instance, the charging record includes the initial charge (A) in the battery, expressed as a percentage of the full capacity, the final charge (B) in the battery at the end of the charging, also expressed as a percentage of full capacity, and the total charging time required (T). Each unit of charge may be, for example, 1% of the full charge of the battery.

Abstract: A method for controlling audio sessions associated with a web browser and an audio endpoint device is implemented at a computer having memory and one or more processors. The computer system provides a unified audio session channel between the web browser and the audio endpoint device, the unified audio session channel including information of an audio session manager for the audio endpoint device and a set of audio sessions that are active on the audio endpoint device. Upon receiving a user instruction for controlling audio outputs of the web browser, the computer system selects one or more audio sessions between the web browser and the audio endpoint device among the set of audio sessions that are active on the audio endpoint device. The computer system then updates the audio sessions between the web browser and the audio endpoint device according to the user instruction.
