Fuzzing for obfuscated phone numbers
The use case in question is to show the partial mobile number to the user:
I like to continue with the mobile phone number that ends with * * * * * * 1 2 3 4 & # 39;
The problem is that we can have colide of the last 4 digits because users have the option to select the last 4 digits of the mobile phone and we are showing multiple options of this type to uniquely identify the option we need from some other mechanism .
The options that I am thinking are:
Option 1: sample 1.2 and the last two digits & # 39; 1 2 * * * * * * 3 4 & # 39;
Option 2: shows the fifth, the sixth, the last two digits & # 39; * * * * 1 2 * * 3 4 & # 39;
Option 3: show the alternative digits & # 39; 1 * 2 * 3 * 4 * 5 * & # 39;
Option 4: shows the last 4 digits & # 39; * * * * * * * 1 2 3 4 & # 39;
Problem in option 4 for our country / target market, there is a high collision for a given user, since you can choose the last 4 digits.
In my use case, in the user interface I plan to show multiple options to the client to use one of the inscriptions made previously.
Something like this:
1. Use your account with mobile number 5647 234 4567.
2. Use your account with mobile number 7868 456 7891.
3. Use your account with the mobile number 4321 321 1989.
But instead of showing the full mobile number on the screen, we want to show the queue or partial number. The question here is in which part the best option to show it to the user, so if we select option 1, that is, we show the first and the last two and we mask others. It will look like this.
- Use your account with mobile number 56 ** *** ** 67.
- Use your account with mobile number 78 ** *** ** 91.
- Use your account with the mobile phone number 43 ** *** ** 89.
