What is PYMK algorithm - How and Why Facebook says People You May Know

How does facebook know who to recommend, who you might know, even if you have not met them?

Answer is simple, you only gave contacts to Facebook! 

Mobile to Mobile

If both friends add the same school or college in the education tab, then they will be shown, as you may know on each other.  Or if you have a large number of mutual friends then Facebook guesses that you people might know each other! Clever logic isn't it?

People You May Know

You have synchronised your phone address book to Facebook. It’s part of the permissions you allow it while installing the Facebook App, on your smartphone. So, if you saved a Courier or a random vendor's number there, Facebook will consider as PYMK - and his name will soon appear as a recommendation, People You May Know.

Another way Facebook finds your possible friend is based on Camera metadata. If two people posts pictures that seem to be similar, for example, they could be friends of friends. Or, if the pictures have lens scratches, or dust in the same spots, they must have been shot with the same camera. Facebook robot thinks you may know the other photographer.  For instance, all the people a wedding photographer has shot (with the same lens) will start showing up in one another’s friend recommendations - P Y M K - People You May Know!

This Facebook feature is not new, actually TEN  Years old technology that helps you find a lost friend. However, I have a another kind of challenge that is, I have reached limit of 5000 Friends.  So unless I UN-Friend someone, I cannot add, even if I want to. I have to remove some sleeping friend to add more active friend.  Anyways, I have created a Facebook Public Figure Page, where there is no limit of FANS who LIKE my Page.

Facebook uses the latest Artificial Intelligence, Machine Learning, predictive analysis, and Big Data for the PYMK.

WHY?

Facebook is a # 1 digital marketing company in the world!  It is in Facebook interest to have people connected so they can sell market research, demographic data, and cater to you as an individual. Targeted advertisements are the main source of revenue.  So it makes sense Facebook robot will do anything,  to build people's connections. 

FaceBook does not purposely intend to injure anybody with their recommendations. It is up to you to add Friend or not.

Is WhatsApp sharing Mobile number with Facebook?

This post is regarding WhatsApp and sharing of Mobile number with Facebook, with your permission, of course! 

Users were happy to use it free.  Now we know the reason.

Here is a note by Jyotindra Zaveri based on various blogs by Facebook, WhatsApp, etc.

Facebook acquired WhatsApp in February 2014. And kept free of charge.

"In a time of Universal deceit, telling the truth is a revolutionary act"

1. WhatsApp has announced that it will start sharing your phone number with its parent company Facebook.  

2. As stated by WhatsApp in its recent blog post, it is sharing your phone number with Facebook to “improve your Facebook ads and products experiences.”  It implies that you will start receiving more relevant ads on Facebook and get better friend suggestions. Which I think is good. 

3. The Privacy Policy also states “By coordinating more with Facebook, we’ll be able to do things like track data about how often people use our services and better fight spam on WhatsApp.” This could mean that data such as your mobile’s Operating System, mobile country code, carrier code, screen resolution, and device identifier will also be shared.

4. Your number will be shared with Instagram (also a Facebook company). 

5. FAQ: can you prevent WhatsApp from sharing your mobile number with Facebook?

Answer by Jyotindra Zaveri: YES you can. 

You might have agreed already, if so, you can slide the green button as shown below (here is the catch, within thirty days):

• Uncheck the green box 

• Unchecking means that you do not want WhatsApp to share your number and other data for Facebook advertisements and product-related purposes. Tap on ‘Agree‘.

Additional note:

If you have already agreed to the new terms and conditions, you still have 30-days to reverse your decision.

Open WhatsApp > go to Settings > Account > Uncheck the box given against “Share my account info…”

If you do not see this option under Settings > Account, there’s no need to panic. It means that you haven’t updated to the latest version or you are yet to receive the notification about the new terms and conditions.

6. The secret is that the above “opt-out” procedure is partial. 

This only prevents WhatsApp from sharing your data for Facebook ads and product-related purposes. 

However, your data will still be shared for other purposes which the company puts as “improving infrastructure and delivery systems, understanding how our services or theirs are used, securing systems, and fighting spam, abuse, or infringement activities”.

7.  Good part is that the data-sharing update does not affect your communication on WhatsApp (messages, photos, videos, voice messages, and calls) which continue to be encrypted. This means that they can only be viewed by you and the person you are sending them to.

8. Super secret is:  Users who have agreed to the new terms and conditions still have 30-days to express their disagreement.  After 30 days, once this window expires, they won’t be able to opt out.

9. WhatsApp hasn’t provided a comprehensive list of the types of user data it intends to share with Facebook nor anything about how Facebook will be using this data.

10. Finally:  Don't worry too much, like it or not, with or without your permission; your personal information is already with most IT Giants.  Microsoft started the practice many years back (Remember Windows?), followed by Google, and now Facebook.  The whole technology is referred as BIG DATA. Yes, the database thus crested is a gold mine for advertisements, great revenue source for them. 

So, what if you don’t have a Facebook account?  Your number will still be shared by Whatsapp with Facebook, even if you are not on Facebook. Even if Facebook has your number, it is great use to them. However, your number will not be used to create an account on your behalf. 

Conclusion: Stay cool and might as well enjoy free services.  You and I cannot do about anything about IT (Pun?).

Read the book by George Orwell: Book title is 1984.  If you have read '1984' by George Orwell you will know all about 'Big Brother is watching you'!
