In the embodiment of the application, the message sender can send the message to the outside through telephone communication, internet communication and the like.
In one of the practical application scenarios, when the message sending direction sends the message to the outside, in order to ensure accurate and safe transmission of the message, the identity of the message sending direction (the message sender) is recorded in the sent message, so that the message receiving direction can receive and verify the message according to the identity.
In detail, the identity is used to identify the sender to send identity information, for example, when the message sender sends a message through telephone communication, the identity may be a telephone number; alternatively, the identity may be an IP address when the message sender sends the message via internet communication.

Specifically, the message may be divided into a plurality of fields according to a preset separator, and the fields are numbered according to the position of each field in the message, for example, there is a message "qwe, asd, zxc", and when the preset separator is "the message may be divided into three fields of" qwe "," asd "and" zxc ", and the three fields are numbered, so that" qwe "corresponds to number 1," asd "corresponds to number 2, and" zxc "corresponds to number 3.
Further, the step of extracting the preset message field in the message is consistent with the step of extracting the identity of the sender in the message, which is not described herein, where the preset message field is a field in a fixed location in the message, and the preset message field may be a preset receiving time standard value, or the preset message field may be a preset sending verification value.
In this embodiment of the present application, when a message sender sends a message to the outside through a telephone communication method, an internet communication method, or the like, for the purpose of analysis and transmission efficiency of the message, the fields containing the information are often sequentially generated into communication data, that is, fields at different positions in the message often record information with a fixed meaning, for example, a field with a number 1 in the message is used for recording the identity of the sender, and a field with a number 2 in the message is used for recording the content of the message, or the like.
Therefore, after numbering the fields in the message, the embodiment of the application can obtain the sender identity in the message by selecting the fields with preset numbers.

In one embodiment of the present application, the calculating the offset time standard value of the receiving time standard value is that a preset time period corresponding to the receiving time standard value is offset forward by a delta time, where delta is the maximum network delay of the message sender and the message receiver when each communication is performed.
For example, if the preset time period corresponding to the transmission time standard value is [ Gap i, gap i+delta ], the preset time period corresponding to the transmission time standard value is shifted by [ Gap i-delta, gap i ].
