As of the update of Personal Data Protection Act in 31 Aug 18 from https://www.pdpc.gov.sg/
I want to give you some guidance on how to protect your personal data due to new regulation of disclosing our identity number and images information in Singapore.
Firstly, you will need to spend money get a second mobile number to maintain it, this second mobile number can be insert into same mobile phone and it should work to receive and doing outgoing phone calls and text SMS if not can buy second phone for this usage. You never disclose your primary contact number to very close one even for work purpose at all. If emergency, also cannot disclose your primary number, should be someone who is very close to you too. Leave your primary number disclose to very closed one your loves one like friends for example. Now phone that can have two SIM card for two numbers are very cheap, cost three hundreds plus Singapore Dollars maybe with a local set full one year manufacture warranty right now. We do not need to use memory card to put in phone as I hardly use it, as got cloud service in phone online, additionally also have google or apple cloud service online to backup some stuffs in our phone.
The second number should be using it for work, apply job, like some organization for religion and if you use their product and service usage later on. If you somehow change the second number for at least like every month once, organization should send you e-mail like personal e-mail address to contact you instead if they cannot contact your number. Organization should just send one time reminder to your e-mail if they did not receive a reply from you like a few days later that all.
Identity number should be with last 4 characters only like 123A for example, remember to update all of your documents before you send out now like resume.
An Example for usage like writing resume.
A: Do not disclose your full name, only your surname at most with your English name similar to other kinds of religion name.
B: Birth date should be edited to year of birth, also do not disclose your birth date instead.
C: Address should not be disclose in full also, just put Ang Mo Kio for example.
For the D will be the phone number and E Identity number also.
The reason for doing A to E as above is due to there are too many issue with job agency doing head hunting so trying to safe guard. If head hunting call you to release a lot of these detail then they can later let you know the job information before they can submit for you, kindly reject them so that they can find a better people suited for their job recommendation. I will have to send resume now that I rested one week after my last day which is last month end, will avoid these kind of head hunter specialists as much as I can to slowly find job.
