    • A method and an apparatus for data transmission between a contactless front element and a security element are provided. The method includes: the contactless front element transparently transmits first data obtained from a contactless identification device to the security element through a single wire connection; the security element processes the first data to generate second data; the contactless front element transparently transmits the second data obtained from the security element through the single wire connection to the contactless identification device. Compared with the prior art, the method can transmit the contactless data in real time between the contactless front element and the security element. Thus the security element can directly respond instructions sent by a proximity coupling device during simulating Proximity Integrated Circuit Card, so that the contactless front element becomes a transparent transport channel, the time order compatibility problem can be avoided, and the safety problem can be surmounted.
    • 提供了一种用于非接触式前部元件和安全元件之间的数据传输的方法和装置。 该方法包括:非接触式前部元件通过单线连接将从非接触识别装置获得的第一数据透明地发送到安全元件; 所述安全元件处理所述第一数据以产生第二数据; 非接触式前部元件通过单线连接将从安全元件获得的第二数据透明地发送到非接触式识别装置。 与现有技术相比,该方法可以在非接触式前置元件和安全元件之间实时传输非接触式数据。 因此,在模拟接近集成电路卡期间,安全元件可以直接响应由邻近耦合装置发送的指令,使得非接触式前部元件变为透明传输通道,可以避免时间顺序兼容性问题,并且可以克服安全问题。

    • The present invention provides a method and apparatus for establishing a chat group. The method performed by a server includes: obtaining an identifier of a user of a first client terminal, an identifier of a chat group to be established and a geographic position of the first terminal; beginning to establish a chat group; selecting at least one second client terminal from a predetermined geographic scope; and inviting a user of the at least one second client terminal to the chat group; receiving authentication information input by the user of the second client terminal from the second client terminal; determining whether the authentication information is correct; if the authentication information is correct, adding the user of the second client terminal into the chat group; and sending information of the second user to the first client terminal; finishing establishing the chat group when a preset finish condition is met.
    • 本发明提供一种用于建立聊天组的方法和装置。 由服务器执行的方法包括:获取第一客户终端的用户的标识符,要建立的聊天组的标识符和第一终端的地理位置; 开始建立一个聊天组; 从预定的地理范围中选择至少一个第二客户终端; 以及向所述聊天组邀请所述至少一个第二客户终端的用户; 从所述第二客户终端接收由所述第二客户终端的用户输入的认证信息; 确定认证信息是否正确; 如果认证信息正确,则将第二客户终端的用户添加到聊天组中; 以及将所述第二用户的信息发送到所述第一客户终端; 当满足预设完成条件时,完成聊天组的建立。
