    • The present invention relates to a portable wireless terminal, and in particular, a portable wireless terminal such as a cellular phone, etc., and its security system that can reliably prevent, by remote control, improper use of the portable wireless terminal by a third party when it is lost or stolen. The portable wireless terminal that uploads backup data to a center by remote control from the center via a wireless network includes: a data access control section 1-1 that, in response to an instructions from the center, prohibits access to the backup data retained by a portable wireless terminal or deletes the backup data; an encryption section 1-5 that encrypts the backup data by using a public key notified from the center or a public key owned by the portable wireless terminal itself in response to instructions from the center; and a data transmission section 1-2 to 1-4 that transmits the backup data split into a plurality of data fragments on a plurality of communication paths to the center according to transmission priority of the backup data that is notified from the center or owned by the portable wireless terminal itself.
    • 便携式无线终端技术领域本发明涉及一种便携式无线终端,特别涉及便携式无线终端(诸如蜂窝电话等)及其安全系统,其可靠地通过远程控制来防止第三方便携式无线终端的不当使用 失败或被盗时的派对。 通过无线网络从中心通过远程控制将备份数据上传到中心的便携式无线终端包括:数据访问控制部分1-1,响应于来自中心的指令,禁止访问由 便携式无线终端或删除备份数据; 加密部分1-5,其通过使用从中心通知的公钥或便携式无线终端本身所拥有的公开密钥来响应于来自中心的指令来加密备份数据; 以及数据发送部分1-2至1-4,其根据从中心通知的备份数据的传输优先级或者由中心所拥有的备份数据的传输优先级将分割成多个通信路径的多个数据片段的备份数据发送到中心 便携式无线终端本身。
