Provided is a user privacy management apparatus and method on a Secure User Plane Location (SUPL) network including a SUPL Location Platform (SLP) and a SUPL Enabled Terminal (SET) and performing privacy authorization according to location of the SET, wherein when the location of the SET is calculated, the SLP (or SUPL Positioning Center (SPC) within the SLP) checks a privacy setup according to the calculated location, thereafter queries to a SET user whether to execute the privacy setup using a SUPL INIT message or a SUPL NOTIFICATION message, and then executes the privacy setup according to queries and responses transmitted through a SUPL START message or a SUPL NOTIFICATION RESPONSE message, whereby a user privacy can be managed more stably by notifying a user of the privacy setup according to the location of the user for reconfirmation.

The invention provides a bus arrival time prediction system and method based on multi-user cooperation. The system comprises a plurality of pieces of intelligent mobile equipment and a background server. The method comprises the following steps: a plurality of users position the geographic positions of the users in real time through the intelligent mobile equipment; the background server performs positioning on the basis of a bus route; the background server performs arrival time prediction; the background server performs arrival time prediction result correction; an arrival time prediction result is displayed on the intelligent mobile equipment in real time, and the current relative positions of the users on the bus route are displayed to the users in real time; when the users arrive at target bus stations, corresponding intelligent mobile equipment stops submitting the geographic position information to the background server. The intelligent mobile terminal is adopted instead of professional equipment, so that the implementation cost is lowered; data is acquired for analysis in a multi-user cooperation way in the running process of a bus, and the bus arrival time is dynamically predicted in real time, so that the system and the method have the characteristics of easiness in use and protection of user privacy.

The invention provides a safety monitoring method, an electronic device, an air conditioner and a computer readable storage medium. The method comprises the steps of obtaining first depth data corresponding to a detection area detected by a depth camera; judging whether a target behavior appears in the detection area according to the first depth data; and if the target behavior appears in the detection area, executing a preset processing operation. The depth data is collected through the depth camera to avoid exposure of indoor environment information and image information of the user, so that the influence on user privacy during data leakage is avoided, and meanwhile, the target behavior can still be monitored based on the data.

The embodiment of the invention discloses an object recognition method and system, electronic equipment and a readable storage medium. The object recognition method comprises the steps that a plurality of depth camera devices acquire point cloud frames at different time points, and the point cloud frames comprise at least one object; screening out a target object from at least one object in the obtained point cloud frame of the specific time point through a specific camera device in the plurality of depth camera devices, and reading features of the target object; and based on the features of the target object identified by the specific camera device in the obtained point cloud frames at different time points, determining a depth camera device which identifies the target object again after the target object disappears from the point cloud frames obtained by the specific camera device, the features of the target object can be recognized under the condition of guaranteeing user privacy under the condition of pedestrian recognition.

The invention discloses an information recommendation method and system, which are applied between a client and a server. The method comprises a user information collection step: the client divides user information into a plurality of user information groups, and independently stores the user information groups; a request sending step: when a user initiates a recommendation request at the client, the client extracts at least one group in the user information groups for random splicing, and after generating at least one user information combination, the user information combination is encrypted and sent to a server side; and a recommendation result step: after the server side decrypts the user information combinations, randomly distributing each user information combination to a plurality of recommendation servers, and returning a recommendation result to the client based on the user information combinations by the recommendation servers to finish information recommendation to the user. According to the method, dispersed storage of user privacy data is realized, and meanwhile, the recommendation effect of a recommendation system is considered.

The invention relates to a display screen control method and device and a storage medium. The method comprises the steps that when a display screen of the mobile terminal is in a working state, radar waves are transmitted, and echoes of the radar waves are detected; determining whether a target user exists in a set range of the mobile terminal or not according to emission parameters of radar waves and echo parameters of the echoes; and if the target user does not exist in the set range, turning off and locking the display screen. According to the method and the device, when the display screen of the mobile terminal is in the working state, the radar waves are transmitted, the echoes of the radar waves are detected, and then the display screen of the mobile terminal is extinguished and locked when it is determined that no target user exists in the set range of the mobile terminal according to the transmitting parameters of the radar waves and the echo parameters of the echoes. On one hand, the power consumption of the mobile terminal can be reduced by turning off the display screen; and on the other hand, by locking the display screen of the mobile terminal, the risk of user privacy disclosure can be reduced.

The invention provides a hierarchical authorization method, which is applied to a mobile terminal, and comprises the following steps: when identifying two-dimensional code information of a first user,obtaining security information of the first user; determining a security level of the first user based on the security information of the first user; and determining an authorization level of a second user according to the security level of the first user, and generating corresponding authorization information based on the authorization level of the second user so as to transmit the authorizationinformation to the first user. The invention further provides a mobile terminal and a computer readable storage medium. In this way, the authorization level of the second user can be determined according to the security level of the first user to generate the corresponding authorization information, so that the user privacy is protected, and the user experience is improved.
