Android Video Encryption & Sharing

Abstract:

The project “Android Video Encryption & Sharing” aims to develop a secure Android application that enables users to encrypt videos before sharing them over various platforms. With the increasing need for data privacy and protection, especially for multimedia content, this application ensures that only authorized recipients can decrypt and view the shared videos. The application utilizes advanced encryption algorithms to protect video files, offering a seamless user experience while maintaining robust security standards. This project addresses the growing concern over unauthorized access to sensitive video content by providing an easy-to-use solution for secure video sharing.

Existing System:

In the current landscape, most video-sharing platforms do not provide native end-to-end encryption for video content. Users generally rely on external encryption tools or secure messaging apps that may not specifically cater to video files. Existing systems may also face challenges such as limited file size for encryption, lack of user-friendly interfaces, and inadequate integration with popular social media and sharing platforms. Moreover, the current solutions often require multiple steps for encryption and decryption, which can be cumbersome for users.

Proposed System:

The proposed system is an Android application that integrates video encryption and sharing functionalities within a single platform. It simplifies the process of securely sharing videos by allowing users to encrypt their videos directly from the app before sharing them through various channels. The application supports multiple encryption algorithms, giving users the flexibility to choose the level of security they need. The decryption process is streamlined, requiring minimal effort from the recipient, ensuring that only authorized users can access the video content. This system also includes features like secure key management, encrypted video previews, and integration with popular messaging and cloud storage services.

Methodologies:

1. Requirement Analysis: Identify the security needs and user requirements for video encryption and sharing on Android devices.
2. Design & Architecture: Develop the system architecture, focusing on secure video encryption methods and a user-friendly interface.
3. Encryption Implementation: Implement strong encryption algorithms such as AES (Advanced Encryption Standard) for video files.
4. Key Management: Develop a secure method for generating, storing, and exchanging encryption keys between users.
5. Integration: Integrate the encryption module with Android’s media sharing APIs to allow seamless sharing of encrypted videos.
6. Testing: Conduct extensive testing to ensure that the encryption process does not degrade video quality or cause performance issues.
7. Deployment: Deploy the application on the Google Play Store with clear instructions on usage and security practices.

Technologies:

1. Android Studio: For developing the Android application.
2. Java/Kotlin: Programming languages for Android development.
3. AES Encryption: To encrypt video files securely.
4. SQLite/Realm: For secure storage of encryption keys and other sensitive data.
5. Firebase/Google Cloud: For backend services like authentication, cloud storage, and real-time database for sharing encryption keys.
6. OpenCV/FFmpeg: For video processing tasks, if required, before encryption.
7. Retrofit/Volley: For network communication and integration with cloud services.
8. JUnit/Android Testing Library: For testing the application to ensure reliability and performance.
