Further, after determining that the chain shield is inserted into the digital money wallet, the system detects whether the chain shield has key information corresponding to the login account, specifically, the system identifies the login account of the digital money wallet and acquires account information of the login account. After the account information corresponding to the login account is obtained, the system obtains target key information corresponding to the account information, indexes the target key information in the chain shield by taking the target key information as an index condition, and searches whether key information matched with the target key information exists in the chain shield. Further, if the key information matched with the target key information exists in the chain shield determined through the index, the chain shield provides the key information for signing the transfer information of the digital money transfer, and the system judges that the key information corresponding to the login account exists in the chain shield. On the contrary, if the key information matched with the target key information does not exist in the chain shield determined by the index, the chain shield cannot provide the key information for signing the transfer information of the digital money transfer, and the system judges that the key information corresponding to the login account does not exist in the chain shield. For example: the system recognizes that the current login account is as follows: xiaoming, then acquiring the wallet address in the account information of the current login account: 0xb365064B46AA9d2CdD42B66757FF90a719ef0a32, and acquires key information corresponding to the wallet address in the account information, such as a keystore: { "address": b654321b46aa9d2cdd42b66757ff90a719ef0a67"," crypto ": {" cipher ": aes-128-ctr", "cipherparams": { "iv": 71a741be 75bb242f36262752015c "}," cipherext ": c1408f617d4d0e68a6d61c2e1d37a25608944b1dad88 d 933281a63087c528c0", "cipherext": scrypt "," kdfparams ": {" dklen ": 32", "n":65536 ", p":1 "," r ": 8", "salt": 08a3a 45eda 8186bb 8186b 3353 b 19 b 10142 b 19 f 19 b 3532 ": 19 b 3519 f 19 b 3519 b 35 f 19 b 3519 b 19 b 35 f 19 b 359 b 3532" } b 19 b 35 f 19 b 35 f 44b 35 c 59 b 35 c 59 b 35 b: 62b82fa1e5b640b669f63efc855f4abdcc9bd9eee35110052120324898f 12345. Further, the private key in the target key information and the keystore are used as an index condition, the index is performed in the chain shield, whether the key information matched with the private key and/or the keystore exists or not is searched, specifically, a character matching method can be adopted to compare the characters in the private key and/or the keystore with files stored in the chain shield, and if the key information completely matched with the characters of the private key and/or the keystore exists, it is determined that the key information corresponding to the login account exists in the chain shield. And if the key information which is completely matched with the characters of the private key and/or the keystore does not exist in the comparison, judging that the key information corresponding to the login account does not exist in the chain shield.
In this embodiment, whether key information corresponding to a login account exists in the chain shield is detected, whether key information for signing transfer information of digital money transfer exists in the chain shield is judged, the transfer information is signed through the key information, and the signed transfer information can be verified only by a user corresponding to the key information, so that the security of digital money transfer is improved.
