Methods and systems are herein provided for judder adjustment. In one example, a system comprises a display device configured to display scenes of a major motion picture and a user interface; and a computing device including a processor communicatively coupled to the display device, wherein the computing device is configured to execute instructions stored in non-transitory memory that, when executed cause the processor to obtain and display a scene within the user interface, interpolate frames for one or more of a plurality of input frames of the scene based on a selected judder angle, wherein the selected judder angle is selected via an adjustable dial of the user interface; and display the scene with a perceived judder resulting from the interpolated frames.

A method is provided that protects electronic Identity information based on key derived operation. The method includes using an electronic Identity server to send an application derived identifier of the application and user electronic Identity code to a host security module that randomly generates an application master key, encrypts the application derived identifier with the application master key, and gets an application encryption key. The host security module encrypts the user electronic Identity code with the application encryption key, and gets an encryption document. The electronic Identity server codes the encryption document and an application identity code, and gets an application electronic Identity code. The electronic Identity server uses the application electronic Identity code as the user identifier.

A method for generating and check-controlling a network identity identification code in a network electronic identity is provided for the establishment of a unified network identity management and service ecosystem that effectively protects the network application security and identity information privacy of citizens. A server performs initialization and generates and distributes random numbers while receiving and auditing a request to generate a network identity identification code from a client. If the client passes the audit, encryption coding is performed and a network identity identification code is generated and sent to a network electronic identification card through the client. The network electronic identification card performs check processing of the network identity identification code, and feeds back a result to the server. The server stores the network identity identification code into a database, and informs the user.
