Abstract: Disclosed are an electronic device for obfuscating user data and a server for decoding the same. A method for controlling an electronic device according to the present disclosure comprises the steps of: acquiring a security parameter according to data transmitted to an external server; applying an obfuscation algorithm to the data by using the security parameter; and transmitting the data, to which the obfuscation algorithm has been applied, to the external server. Furthermore, in connection with a method for controlling a system comprising an electronic device for obfuscating data and a server for decoding the same according to the present disclosure, a method for controlling the electronic device comprises the steps of: inserting a fingerprint into data; generating multiple pieces of split data having a preset first size on the basis of the data into which the fingerprint has been inserted; applying an obfuscation algorithm to one piece of split data selected from the multiple pieces of split data by using a preset security parameter; and transmitting the split data, to which the obfuscation algorithm has been applied, to the server. In addition, a method for controlling the server comprises the steps of: receiving the multiple pieces of split data, to which the obfuscation algorithm has been applied, from the electronic device; acquiring at least one piece of candidate data on the basis of the received multiple pieces of split data, to which the obfuscation algorithm has been applied; and acquiring data comprising the fingerprint among the at least one piece of candidate data.

Abstract: According to an embodiment, an electronic device includes a memory, a first processor coupled to the memory and configured to control the electronic device in a normal execution environment (REE), and a second processor coupled to the memory and configured to control the electronic device in a secure execution environment (TEE). The first processor in the REE may be configured to transfer, to the second processor in the TEE, a request for generating a block including verification data of a data chunk. The second processor may be configured to generate the verification data of the data chunk by using key information of the electronic device, sign the verification data, and transmit, to an external electronic device, the block including the signed verification data.

Abstract: An electronic device is provided. The electronic device includes a camera, a memory configured to store a model learned to determine whether a user performing authentication for a financial service is in a threat situation, and a processor configured to perform authentication for the financial service based on biometrics information of the user performing authentication for the financial service. The processor may acquire an image by photographing the user performing authentication through the camera, acquire information on whether the user performing authentication is in a threat situation from the learned model, with information acquired from the image as input of the learned model, and perform authentication for the financial service according to the acquired information. At least a part of the learned model is an artificial intelligent algorithm, which may be performed according to at least one of machine learning, neural network, or deep learning algorithm.
