This allows developers to perform operations on sensitive information without exposing it, ensuring data privacy and security. Key Features and Functionality: - Homomorphic Encryption Schemes: Supports the BFV scheme for exact computations on encrypted integers and the CKKS scheme for approximate computations on encrypted real or complex numbers. - Cross-Platform Compatibility: Written in standard C++ with no external dependencies, making it compatible with various operating systems, including Windows, macOS, Linux, and Android. - Compression Support: Offers data compression using the DEFLATE algorithm to reduce memory usage when serializing objects like encryption parameters and keys. - .NET Support: Provides a .NET Standard library for seamless integration into .NET applications. Primary Value and Problem Solved: Microsoft SEAL empowers developers to build applications that can process sensitive data while maintaining confidentiality. By enabling computations on encrypted data, it eliminates the need to decrypt information, thereby reducing the risk of data breaches and unauthorized access. This is particularly valuable in sectors like healthcare, finance, and cloud computing, where data privacy is paramount. ## Microsoft SEAL Reviews ### 1. A great beginning. Microsoft Seal is the next step in encryption based tech platforms. **Rating:** 4.0/5.0 stars **Reviewed by:** Ayushman M. | Student, Enterprise (> 1000 emp.) **Reviewed Date:** May 15, 2022 **What do you like best about Microsoft SEAL?** I found Microsoft Seal to be a powerful library that meets almost all data processing needs of any organization. The fact that it is built on a homomorphic encryption system, makes it a truly delightful experience to use. Since data can be directly processed while being encrypted, it gives our clients greater confidence over system security and confidentiality. **What do you dislike about Microsoft SEAL?** Homomorphic encryption still needs to evolve. There remain many issues related to the load on the system, the resources being consumed while processing data etc. These issues need to be resolved to make Microsoft Seal better. **Recommendations to others considering Microsoft SEAL:** Be aware of the benefits and disadvantages that come with using homomorphic encryption **What problems is Microsoft SEAL solving and how is that benefiting you?** Data confidentiality and security is the most important benefit that we are realizing with Microsoft Seal. Our clients too feel reassured about their data. Moreover, the library is powerful enough that we do not feel at any point that a compromise is being made by not decrypting the data and then processing it ### 2. Breakthrough technology in data storage and processing **Rating:** 4.0/5.0 stars **Reviewed by:** Ankesh K. | Software Engineer III, Enterprise (> 1000 emp.) **Reviewed Date:** June 30, 2022 **What do you like best about Microsoft SEAL?** it helped to store and process sensitive data on Azure cloud service without exposing it to the cloud provider. While doing POC on handwritten tweets our main challenge was to keep the signatures of individuals safe. Seal comes as a perfect solution as it provides one additional security on top of the private cloud. we don't have to expose data even to cloud providers. **What do you dislike about Microsoft SEAL?** Technology is still growing so it's slightly slow to use. It would have been good if it had the analytical ability on encrypted data so that we could have given a third party to analyze data without exposing them to real data. **What problems is Microsoft SEAL solving and how is that benefiting you?** it is putting an extra layer of security on top of the private cloud. ### 3. Microsoft seal library review **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** September 08, 2022 **What do you like best about Microsoft SEAL?** The best library where we can store all our secret keys, private keys etc securly in cloud. The best part is the security of data which is sealed and secured **What do you dislike about Microsoft SEAL?** Nothing as of now. Seems works perfectly for our requirements **What problems is Microsoft SEAL solving and how is that benefiting you?** Data security which is a concern because prev we used to store secret n private keys in sourcecodes but now it's not that case. We are storing all our secure keys in seal ### 4.
