Can you think of aything else? Now lets assume the company sells off your data to a third party. What extra will you do apart from going to the consumer protection bureau? Let's be practical!
Don't have any list, this is just a general idea first and sees how it develops with the input of many other clever, thinking, creative minds here!
For the first one you suggested, it should be for both physical person full name, and company/corporation names, and if it is a corporation or business name, which it has a big list of all its members behind, which normally companies have always their member's name hidden, which need to be always upfront available to anyone to verify who they are.
For the second question about what to do when a company is selling people's data... As we know we are still in a new field, where there are few options for the clients to do when things like that happen. But I am sure this will soon be different if people keep talking and bring new ideas to stop the abuser from selling personal data!
No buddy, you are not getting my point here! We can ask N numbers of KYP data from our providers. Including how they are storing our data and who all are having access to it etc. But my point is that, how do you prove that a company sold off your data to a third party? What action would you take after knowing that fact? Remember, we are free to go to consumer protection forum at any point of time. But how do we prove that that company actually sold off our data? It's a big gap!
