Automatic Cleaning of SMS messages

Technical Background:

Mobile phones are widely used. When using mobile phones, text messages are also an indispensable part of text communication. Many text messages are sent and received, which may involve privacy, confidentiality, and security. If the text message content is accidentally lost on the mobile phone, or the mobile phone is accidentally peeked at the relevant information, we usually Delete the text message content manually, it is a little complicated or you forget to delete it, which makes it unnecessary. Therefore, an automatic cleaning method can save us a lot of unnecessary worries and concerns.

Technical content:

Generally, text messages are generated by sending and receiving operations. Common mobile phones have inbox folders. Some smart phone messages are automatically classified based on the user's contacts, all the sending and receiving information is classified under the contact.

In any case, we need to clear the sent text message. This technology includes the record module, storage module, detection module, reminder module, automatic deletion function module, and encryption module.

The record module records the information of the specified time period and the contact's message sending and receiving time. It also records the information of the contact and the sensitive keywords involved in the information, such as the keyword of misdemeanor, financial property, and money, and business. secret, password, verification code, ID card, phone number, and so on.

The preset time period information is mainly set based on this method. For example, the fixed time period is 60 seconds. Generally, it takes enough time to read a text message within one minute.

The detection module monitors the contact's contact time and preset time period, and detects whether the SMS sending and receiving time exceeds the preset 60 s in this time period, if it is detected that the time of receiving or sending the text message exceeds the preset 60 seconds, and the deleted message cannot be deleted automatically based on the read and unread status in the inbox. At the same time, the detection module also needs to search for unread information that involves sensitive keywords, as well as for the sent information.

If sensitive keywords are retrieved, the system sends an instruction to the reminder module prompting the user to process unread and sent information as soon as possible within the specified period of time, (the specified time period is different from the previous time period. This preset time period is specific to the time set for unread information and sent information, such as automatic setting of unread information and sent time periods. one day is the time from receiving to the current system and the time from sending to the current system is 24 hours ).

If the system detects that the data has not been read within the specified time period and detects that the data has been sent beyond the specified time period, the encryption module encrypts and backs up the data based on the information provided by the detection module, encrypted backup is mainly implemented based on the preset mobile phone encryption principle. As long as mobile phone encryption is set and private SMS information is encrypted at the same time, you can decrypt and read private SMS messages through mobile phone decryption, this is also true for sent privacy information.

If you do not want to retain the sent privacy information, you can delete it.

The system immediately finds out whether to delete the read messages based on the information stored in the reminder module (mainly sending and receiving contacts and storing the time, if you select Delete, the information is automatically cleared. If you want to save the information, you can save the information to the mobile phone or storage card based on the existing saving function of the SMS to back up the information.
