Generally speaking, first of all, the enterprise should clarify the confidentiality obligation and scope with the employees, that is, clearly inform the employees of what needs to be kept confidential, and the employees agree to keep it confidential. In addition to the above materials, the technical secrets leaked by enterprises do have confidential value. If the above is established, then the responsibility for leaking secrets can be investigated. If one of the above is not true, then he can't be held accountable.
For example, when employees of an enterprise join the company, they are informed in writing in the enterprise secrecy system that the relevant technical data of the enterprise need to be kept confidential, and a catalogue of confidential matters is listed, requiring employees to sign a confidentiality agreement, stipulating the confidentiality period and confidentiality responsibilities. One of the confidential matters is the enterprise address book. After the employee left the company, some address books were leaked to others. At this time, you can't hold him responsible for confidentiality. Because although the agreed address book is confidential, the address book has no confidential value.
The so-called confidential value means that only a few people in the enterprise know it, and it has economic value, patent right, or unique advanced technical information and so on. Obviously, the address book has no confidential value. But if he leaks a patented technology in the confidential list, then he can be held accountable for confidentiality. However, if he is not informed of the confidential matters during his tenure or when he leaves his post, and he does not know that this thing needs to be kept confidential, then he does not need to bear the obligation of confidentiality.
