- 2. Project Scope • Privacy • Secure • Purpose of Encryption • What is Encryption
- 3. Requirements • Hardware – Processor : i3 or above. – Processer speed : 3.00GHz – Hard disk : 300GB – RAM : 4 GB or above – Monitor : super VGA(17 inch) – Keyboard : Logitech (103 keys) – Mouse : Logitech or Optical
- 4. • Software – IDE : Android Studio 3.4.1 (Stable) – DB : Firebse – OS : Windows 7,8,10, Linux. – Mobile Os : Kitkat or above Versions – Virtual Box : Genymotion 6.0
- 5. Abstract • Whatscrypt application design which protects its users with better integrity, confidentiality and privacy. • The purpose of the Whatscrypt application is to allow users to communicate and chat securely with each other, to use advanced Encryption algorithoms. • The users will be able to chat with each other, most likely from user to user. Also one user can send one message to many users by forming a group so that all the contacts can receive same message.
- 6. Existing System • Privacy of a user is related to and based on a metadata that an application can collect and send to a second or third party. • Unfortunately privacy is one of the factors that is getting sacrificed in the current mobile application environment. Many applications are free of charge, but the service providers grab metadata of the user and send these information to their servers even sometimes without the knowledge of the users. • Metadata means any type of data which includes different information about a user, such as location, name, contact information, creator of data, contact list, type of operating system, etc….
- 7. Disadvantage of Existing Systems • It not secured privacy issues • Encrypted data can store and retrieve in that system accessing offline • Encrypt algorithms are commonly used • It less integrity • Encryption plays a major role, but decryption plays not match
- 8. Proposed system • The proposed system suggests a new method of how the messages are stored. • This proposed system aims to fill this gap by providing an advanced level of chatting protection algorithms. • This algorithm works with both private key and public key. Only the encrypted file will be uploading to the server. • In this application have protect spams, malware attacks, advertisement.
- 9. Advantages of Proposed Systems • It is more secured for protect spams, advertisement, malware attacks. • Encrypted Data not store and retrieve in that system, save in online Database. • It is more integrity. • ‘N’ no.of users connected with stable performance. • Using new encryption algorithm. • Encryption and Decryption is plays main role.
- 10. Modules 1. Server Module 2. Client Module 3. Authentication Module 4. Discover Friends Module 5. Request Module 6. Conversation Module
- 11. Server Modules:- – A Server is a specially equipped Mobiles connected to the internet that allowsusers with chat clients to converse with one another via typed messages in real time. Client Modules:- – A Client is a Software program that allows users to connected to chat servers and communicate with other users via a chat room.
- 12. Authentication Module • Authentication is one of the most important aspects of security. • This avoids any type of attack or malicious activity by which a malicious user impersonates the user and identifies himself as the real user to the server. • There are different practices to perform such authentication such as one-time passwords (OTP) and certificate-based authentication (CBA). • In one-time password, a shared secret key is stored on a device that the entity has, and the system issues one-time passwords based on this shared secret key.
- 13. Discover Friends Module • The Discover Friends Module is to show all users id and profiles. • The user can who wants to chat when give the request to that user, and also who wants to block chat when user can then remove user from contact list. • User have already request then user can accept that request.
- 14. Request’s Module • The Request’s module is shows who wants to send request and also who wants to user receive requests list are shown. • If user interest to chat that user when accept the request other wise user can cancel requests.
- 15. Conversation Module • The Conversation module is to show the chat contacts. Here we choose who wants to chat (private) to select on the contact. • Once you select contact when instantly create a page and ready to connection chat with that user. • In this page user can type text message and the key for encryption that message will encrypted and sent it. Receiver can decrypt that message using the same key. • Here the another way to secure, don’t have take screenshot or screen recorder at this module.

- 23. Find Friends Page Profile Page Request sent to others
- 24. Request from others Chat Page Individual Chat
- 25. Decrypt Message Using Key View message
- 26. Feedback Page
- 27. Conclusion • Users can be confident that nobody can read their messages; even provider of the service also cannot read their messages. • Even the mobile phone reaches to wrong hands, no readable information can be extracted from the physical memory of the phone.
- 28. Future Enhancement • In future this project can be developed to share the documents, images, audio and video in a secure way and also to provide advanced encryption algorithms to encrypt those multimedia files which has to share securely. • The next level to develop the video conference call and voice conference call will also be included.
