Copyleft

Week-6

What is a copyleft?


Well, to start, in principle, we wouldn't be wrong to say that copyleft is the complete opposite of the term "copyright". If any license has a copyleft term, that usually indicates that it is free to copy, distribute and modify. In other words, it can be said that it is an open-source licensing.


There are two types of the copyleft licenses; strong and weak.

Strong copyleft is meant that even a tiny bit of the code in a program is yours, this would simply imply that the whole program/software must be issued under your name too.

While in weak copyleft, if a software contains some of your code then only certain parts of the license has to be published under your name. And other parts would be licensed under other people who contributed the software, since the software as a whole is the combination and modification of their codes.

Fingerprint information is stored locally in a secure enclave on the Apple A7 and later chips, not in the cloud, a design choice intended to make it impossible for users or malicious attackers to externally access the fingerprint information. Google It began in January 1996 as a research project by Larry Page a...
