Abstract: A multi-modal type wearable user authentication apparatus includes a housing; an electrode plate disposed at a rear surface of the housing to contact a user wrist; a display panel disposed at a front surface of the housing; and a multi-modal type user authentication sensor including mutually separated first and second electrodes disposed at the lower end of the display panel and constituting an edge and a bio recognition module disposed at the center.

Abstract: A multi-modal based user authentication apparatus and method are provided. The multi-modal based user authentication apparatus includes a memory that stores whether user authentication is succeeded or failed; a processor that determines whether user authentication is succeeded or failed through user authentication; and a user authentication sensor unit that performs step (a) of measuring user bio signal information through a bio signal measurement sensor, step (b) of acquiring user bio recognition information through a bio recognition acquisition sensor, and step (c) of performing the user authentication by analyzing a correlation between the bio signal information and the bio recognition information.

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 junk directory identification method and apparatus. The junk directory identification method comprises: obtaining a directory to be identified; wherein, the directory to be identified is a directory generated after running of an application software; obtaining the file names of the files in the directory to be identified; determining whether the file names of the files in the directory to be identified all conform to temporary file naming rule; if so, determining the directory to be identified as a junk directory. Hence, the present solution uses a method of determining whether the file names of the files in the directory to be identified all conform to the temporary file naming rule to identify whether a directory to be identified is junk file, making full use of the unique naming method when a directory automatically created by a software application caches files, and can therefore effectively identify whether a directory in an application software is a junk directory.

Abstract: A method and device for identifying junk picture files, which are used for a server side to identify junk picture files in cached network data. The method comprises: obtaining a directory to be detected; determining whether the number of files in the directory is greater than or equal to a first preset value; if so, determining whether file names of the files in the directory contain keywords which represent the cached network data; if the keywords are contained, determining that the files in the directory are the cached network data, and then, determining whether keywords which represent useless picture files exist in the cached network data, so as to find out whether junk picture files exist; if the junk picture files exist, identifying the found picture files as cached junk picture files; and recording a directory path where the cached junk picture files are located. By means of the above solution, the cached network junk picture files can be accurately identified.

Abstract: Embodiments of the present application provide an application program uninstallation method and apparatus. The method comprises: receiving an uninstallation instruction for a target application program (S101); deleting a specific directory in a local device to which the target application program corresponds, according to the received uninstallation instruction (S102); extracting an identifier of the target application program (S103); searching a local pre-set directory residual database to determine whether there exist any directory data that correspond to the identifier (S104), the directory data comprising at least a directory path; if such directory data exist, deleting a directory in the local device to which the directory path found corresponds, according to the search result (S105).

Abstract: Provided are an apparatus, a system and a method for detecting and preventing malicious scripts. The apparatus for detecting and preventing malicious scripts includes a signature management unit managing a first signature including code pattern information of previously-detected malicious scripts, a script analysis unit receiving the first signature from the signature management unit and analyzing a first script, which is included in a web page, using the first signature, and a script processing unit receiving analysis result data from the script analysis unit and processing the first script according to the analysis result data.
