Background

The role of mobile phones in daily life has become more and more important. The loss of the mobile phone can cause risks to various social accounts and payment accounts, and also can cause loss of personal information such as personal photos and the like. Once the mobile phone is lost, the influence on various aspects of the life of the user is great. In the prior art, a traditional mode of searching for mobile phone signals or appearances is considered, and even if a block chain is combined, photo-like information is only registered and broadcast searching is carried out. However, if the picked up person does not want to return, the user cannot obtain the lost mobile phone. Therefore, at present, most of the situations are that people who lose the mobile phone are picked up, and the mobile phone is often waited for the owner to make a call actively so as to be contacted with the owner. However, sometimes, a person who partially finds out a mobile phone is unwilling to return the mobile phone to a loser without compensation, but wants to pay a fee, and if the fee is not paid, the person can still shut down the mobile phone or even try to crack the password of the mobile phone.

However, in reality, there are many cases where a return person of a mobile phone suddenly changes the divination price on the originally agreed reward to seek higher reward, or does not want to return the mobile phone after receiving the reward, or the owner does not want to pay the reward after obtaining the mobile phone.

In fact, the lost mobile phone has value not only for one mobile phone but also for information and data of a large number for the owner, and for the pickers, the mobile phone is at most only a second-hand mobile phone, and because some existing mobile phones have lost modes, the mobile phone is directly locked, the pickers cannot use the mobile phone, and the mobile phone can be a brick in the hands of the pickers, whether an incentive method for returning the mobile phone can be provided, whether the mobile phone pickers become mobile phone returning persons is encouraged, and the trust problem between the owner and the returning persons can be better solved.
