Patent Searching and Data


Title:
DATA INVOKING METHOD AND DATA INVOKING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/210471
Kind Code:
A1
Abstract:
A data invoking method and a data invoking apparatus which can increase the difficulty of cracking a core dynamic link database. The method comprises: receiving an invoking request for invoking a target dynamic link database of a bar code recognition device by means of a restricted interface (101); determining, on the basis of a random algorithm, whether the invoking request needs to be verified (102); if the invoking request needs to be verified, acquiring an access key by means of a proxy function (103); decrypting the access key using a private key of a preset encryption algorithm to obtain a decryption result (104); performing verification according to the decryption result and a random factor value to verify whether the invoking of the target dynamic link database by using the restricted interface is valid (105); when the verification is successful, determining that the invoking of the target dynamic link database by using the restricted interface is valid (106); searching for, on the basis of the proxy function, an index subscript of a target invoking interface address of the target dynamic link database stored in a target hash table at the current moment (107); and searching the target hash table according to the index subscript for the target dynamic link database (108).
