Abstract: A method for updating security information is applied to a system including an information service provider and mobile devices. The information service provider includes a server and a database, in which the server provides security information to the mobile devices and each of the security information is related individually to a security code. The information service provider can transmit updated security information to the mobile devices in an active-push manner in communicative off-peak hours, and at the same time each of the mobile devices would be automatically waken up and connected with the service-provider so as to receive the updated security information. While the mobile device is to request additional information, the passive-pull transmission manner can then be applied by the mobile device to obtain the additional information from the information service provider. Thus, merits of both the active push transmission and the passive pull transmission can be obtained.

Abstract: A method for transmitting massive data by using dynamically adjusted updating frequencies is employed in an information processing system. The user device dynamically adjusts a level of the data to be transmitted according to an operating condition of the user, such that the server of the information processing system can use different updating frequencies according to different levels of data to transmit wirelessly the data to the user device. The data the user cares more are transmitted by using a higher frequency, while other data the user cares less would be transmitted by using a lower frequency. Thus, the bandwidth consumption can be decreased while in sending data to the user device. The user device can receive and use massive data from the server for performing required mathematic calculations or statistics at the user device so as to decrease the loading of calculations at the server side.
