How to find out who wrote the anonymous letter?

When we receive an anonymous letter, we should first read the contents of the letter carefully and then analyze it carefully according to the contents of the letter. Think carefully about who you have a problem with, who is the most suspicious to write this anonymous letter, and try to narrow down the scope of suspicious people.

Check the handwriting in the letter:

Handwriting and human fingerprints are the same. Everyone's handwriting is unique, not uniform, and it is difficult to disguise. If we receive a handwritten anonymous letter, the handwriting in the letter may reveal the author. When we receive an anonymous letter, it is possible to find out who wrote it by looking at the handwriting.

Compare the fingerprints in the letter:

If the person who writes an anonymous letter is careless and thoughtless, it is very likely that he will leave his fingerprints in the letter. At this time, we can use the fingerprint comparison function, use professional fingerprint authentication institutions to detect, and then compare fingerprints, so as to lock who wrote the anonymous letter.

04 Find the source of mobile phone number:

If we receive an anonymous letter in a short message, we must know the other party's mobile phone number at this time. If the other party sends us an anonymous short message through the registered mobile phone number, we may find out the identity of the other party through the relevant communication department.

05 Find the IP address of the other party:

If the other party sends us an anonymous letter in the form of QQ and other chat tools, first of all, we should carefully check the relevant information of the other party's QQ to see if there is any personal information of the QQ owner on it. If not, you can also find the IP address of the other party in some ways. By looking up the IP address, we can also find out the identity of the author of the anonymous letter.

06 Search for the other party's mail:

If the other party sends us an anonymous letter by email, at this time, we can also check the email information of the other party and determine the person who wrote the anonymous letter through the email information. This method may not be very successful, because the other party may also register email with false information, but it is also a method.

07 seek public security help:

If the contents in the anonymous letter are threatening, it has seriously affected the personal safety of individuals. At this time, we can also choose to call the police, and then use the public security organs to help find out who the owner of the anonymous letter is. Generally, public security departments are more professional, and they are more sure than we are to find out who wrote anonymous letters.
