System And Method For Distributed Authentication Service: Fill & Download for Free

It depends on complexity of systems.For a simple non distributed system HLD can be just logical layering and interaction between them and LLD can be actual class and method structures in those layers.For a big distributed SOA type system with say 50 components HLD could be components involved and interaction between those components (information flow) and LLD could be how individual component owners design their part of the whole puzzle.There can be HLD and LLD in LLDs recursively based on how big a problem you are working on.Just taking a very basic example.A Register/Login system in a web application.In text form HLD and LLD could be vaguely likeHLD1. There would a UI layer to take input from user2. There would be a service layer to do validations, do password encryption, authentication and communication with storage layer3. There will be a storage layer to store the registrations and to match against for logins.LLD1. UI will be 2 boxes and 1 submit button2. Service will be UserService with methods likeregister(User user)login(String username, String password)3. Storage will be a relational db and there will be a table called user with fields as id, username, password.

I can definitely relate to you. The mystery behind screen capture used to irk me too until I researched about it. Though there are some bugs that you can exploit and record screen or take screenshots but under normal conditions you can’t actually capture the screen.Netflix solution is NOT about the code. It is called DRM or Digital Rights Management. It protects the data from any piracy, Including screen records/shots and downloading.Digital Rights Management (DRM) is a term that refers to all technologies used by copyright holders to control the use of digital material they distribute and to limit the use of the content to their intention.It is primarily used to prevent unauthorized use of digital content such as e-books, sound recordings, and videos, by allowing only authenticated users to use the content for the authorized period of time.The functions of DRM are divided into ‘encryption and decryption of contents’ and ‘encryption key management’.By default, the original content is encrypted through a process called ‘DRM packaging’ and passed to the user. Without the encryption key information used to encrypt the content, the user cannot decrypt it for playback.The ‘Encrypted Media Extension(EME)’ specification provides an API that enables HTML / Javascript based web applications running on a web browser to interact with content protection systems (DRM).But still there are cases where these technologies alone can not prevent content leakage., hence we also need forensic watermarking.Leakage case 1 — Screen recording using camcorderOne of the most traditional content leakage cases is the so-called ‘cam version’ footage.This is to record the video played on the screen with a separate camcorder or smartphone camera. DRM technology can not prevent this type of content leakage.This is called Digital-to-Analog (D2A) or Analog-to-Digital (A2D) conversion, one of the attack methods for watermarking.With the increasingly smaller and higher-performing devices, it is now possible to record video with almost the same quality as the original at 4K/UHD resolutions beyond full HD.Leakage case 2 — Video recording through PC screen recorderSupport for DRM content playback through PC web browsers and HTML5 players is one of the most important target platforms for OTT services.However, since some web browsers use software based DRM, you can easily save the DRM video as normal MOV or MP4 format video file by using various screen recording tools.EME (Encrypted Media Extensions) is the standard that allows DRM in HTML5 video. However, the EME spec only specifies the interface that the client-side part of the website uses to access this functionality. It doesn't specify anything about how the media file is encrypted, how it is decrypted, or even how it will be displayed on the client's device. This is determined by the CDM (Content Decryption Module), which is the proprietary part of EME that has caused so much controversy.WebBrowser -> HTML5/Javascript -> EME -> DRMAnd yes, of course you can build your own solution using EME.More information is available at What is EME?
