Pay per API Call Protocol - Part 1

By Vishwas Anand on 2022-05-18

NOTE: This is just my imagination without doing any proper research either on the problem statement or on the protocol. I request you to read this blog keeping that in mind. This is NOT full proof solutinon. Applications share data with each others via APIs. Sometimes, these APIs need to protected behind paywall by the API providers. This is to ensure APIs consumers do not misuse APIs as well as to incure cost of the API services.

Privacy Preserving Social Login Using Hypersign

By Vishwas Anand on 2020-11-16

Introduction Social logins like Facebook, Google are common Single Sign-On (SSO) mechanisms for authentication in websites (also called service providers) these days. The social login helps service providers to quickly onboard a user without requiring them to go through the registration process. This way, on one hand, the service providers can provide seamless onboarding to their user and on the other hand, the user need not to type his details like name, email, phone number, every time he avails a service from a new provider.

Data breaches have become common in consumer-facing apps in India; How Hypersign can help?

By Vishwas Anand on 2020-11-02

Abstract The consumer-facing applications are more vulnerable for data breaches as they have a large customer base and they usually stored the user data in a central location. The consumer-facing app provider often has to choose between security and usability and they end up giving priority to the later one as usability become important growth factor. That allows a hacker to steal user data. In this blog, we are going to talk about problems, challenges which service providers face, especially with respect to user data protection and privacy, and what could be possible ways to solve that problem.
