“This kind of confidential file is locked, and it is impossible to send an email unless you know the unlock password, but no one in the unlock password project team knows. As for the mobile hard disk, the relevant computer has blocked the interface.”

Upon hearing the answer, Qin Feng said.

“In other words, this file can only be obtained through a printer?”

Xiao Tianduan nodded and said.

“Well, yes, if you encounter a situation where you need to use a document, the normal process of “August Seven Seven” should be printed out and then stamped with the official seal. This document missed the step of the official seal, and it must have been printed privately.

Qin Feng asked again at this time.

“Can you find the record of using the printer?”

Xiao Tianduan shook his head helplessly and replied.

“This part has not been found. Although confidential documents like this are confidential, they may also be used when they are needed. Therefore, when printing this section, there are not too many restrictions and no need to unlock. Although normal printing should leave a record, but This record has been deleted.”

Knowing that related records were deleted, Qin Feng said.

“This should be able to restore the print records through data recovery, right?”

Hearing these words, Xiao Tianduan said.

“This is also being done. In fact, the record has been restored, but the current result is useless.”

Qin Feng heard that it was useless and asked suspiciously.

“Why is it useless? If you have a usage record, it should be able to be used to lock out suspicious persons.”

Xiao Tianduan responded on the spot.

“According to the restored record, it is a normal printed record. This confidential document was used normally last month.”

“We also investigated the person who printed it, and we can confirm that he was only printing the documents normally, and later he also stamped the documents he printed.”

This answer made Qin Feng frown.

If there are no other discoveries, it is tantamount to an inexplicable and printed confidential document.

At this time, Xiao Tianduan said again.

“However, according to our investigation, after the person who printed the document printed it out, because of some things, he temporarily put the document aside and he went to work.

“After finishing the work, I only stamped the official seal on the document. I left it for about three minutes in the middle.”

Qin Feng said at this moment.

“That is to say, this confidential document in my hand should have been taken and copied within those three minutes?”

Xiao Tianduan nodded and said

“It should be like this, but we haven’t found out who took the photocopy in this part. At that time, the place where the file was placed was a blind spot for monitoring.”

Hearing that the place where the file was put was a blind spot for monitoring, Qin Feng asked immediately.

“What about the copier?”

Xiao Tianduan immediately responded.

“There is monitoring on the copier, but so far, we have not found any suspicious places.”

This answer also surprised Qin Feng.

According to what Xiao Tianduan just said, the person who copied the document only had three minutes.

Even considering that the person concerned may not directly check the exact time, it was only estimated for three minutes.

The time that can be used will not be too long.

In this case, you only need to lock the person who used the photocopier for a few 2.1 minutes at the time, and you should be able to find the suspicious object.

As a result, Xiao Tianduan said that no suspicious places had been found.

Qin Feng thought for a while, then asked.

“You said you didn’t find a suspicious place. How could this be? Who were the people who used the photocopier in those few minutes?”

When Xiao Tianduan heard the question, he frowned and responded. ,
