Are images/messages shared on WhatsApp stored by cyber crime cells?
WhatsApp has their own Privacy Policy which states that all the data sent are encrypted and only the sender and receiver of the image/text can view its content. How ever, WhatsApp’s Terms & Conditions stricly specify the fact that it does have log of conversations for a period of time, and such data may be shared to Law Enforcement Agencies. That being said, WhatsApp does not give direct access to Law Enforcement Agencies like Cyber Cell to take view logs. It does have a compliance procedure, which has to be followed by the Law Enforcement Agencies for such content to be shared. To put it in short, sharing of any illegal content, when reported, will be taken action, and the cyber-cell can retrieve such data to take legal action.
Is facebook dangerous for someone like me?
Facebook IS dangerous IF you allow everyone to see your profile, your pictures, & you put up personal info. I always have my info set so that only friends can see everything, & I only accept people I know to be a friend on my facebook. On the info section some people put where they live, where they work, their phone number, their email, when they graduated, pictures of themselves & their families, etc, that's a way for Identity theft people to more easily get access to info they need to steal your identity. It's also a way for creeps/stalkers, etc to find where you live to "take advantage" of you or kidnap your children. Most people use facebook to catch up with old friends, keep in touch with their current friends (although I think calling someone should be the proper way), look for dates, brag about your life, play games, just something to do, etc, etc.
When you permanently delete your Facebook account, what happens to your information?
Your data lives in multiple systems within Facebook. Aside from the primary Facebook application, there are systems which are used to analyze and store historical data, such as Hadoop. I can speak a bit to how data is used for measuring Facebook's usage and what happens to old data.At a high level, if you delete your account, it is "logically" deleted starting at the time you've deleted it. Accounts that are deleted are generally not included when calculating metrics going forward. This basically means that if someone asks "How many users do we have", a person who deleted their account wouldn't be included in calculating that.Additionally, there are processes that "scramble" identifiable data once it becomes stale (about 90 days). Things like names and even user id's can no longer be referenced in any decipherable way.To answer the first part of your question, "Could you pay Facebook to properly delete all your information?", assuming "properly" means completely wipe away any trace that you ever existed on Facebook, the answer is no. For two main reasons:Hive (a tool within the Hadoop platform which Facebook uses for analyzing and storing data) literally doesn't allow you to delete individual records from tables. It is simply a limitation of the technology. The only way to delete your data would be to delete everyone's data.Even if you could delete individual records, older data that would allow a person to identify your records is scrambled. No one would be able to tell one person's information apart from any other.For the second part of your question, "how much would it cost?", based on what I explained above you would likely need to own Facebook to make a decision that would impact every single user. At today's closing price, Facebook has a $65 billion market cap. It’s not uncommon to pay on the low end of a 30% premium for companies with growing revenue. So the answer to your question is probably somewhere in the neighborhood of $85 billion to "properly" delete your data.
Once a Facebook account has been permanently deleted, is there any way to find out the IP address of the person it belonged to? What information can you get from a permanently deleted Facebook account?
It depends, As all other companies, Facebook may also have some internal policies, which is not public. In their public policy, they mention they won’t store any deleted information. But some years before a problem was identified that the deleted content are available if we request an archive of profile (in case of active accounts).Another fact is that even the contents are deleted from their severs, it can be recovered if not overwritten (If they permits).But here you are mentioning about IP address. Normally everyone use dynamic IP, which will change on every modem restart, The IP assign will be stored in the database of ISP. But if one have sufficient knowledge, they will do various methods to change their identity (TOR, VPN, MAC spoofing etc are some among them)So just leave it if it is a normal account and you need the details for normal reasons.
What are your best tips for staying safe on the Internet?
We now have some things that didn't exist when I was younger: social networking and cellphones. How should a young person stay safe online? IMVHO, it starts with face-to-face dialogue before the computer is powered up or the cellphone turned on (most cellphones have internet access). --The online names should NOT your own name. Use a nickname or a made-up name. --NEVER open an e-mail or a link from someone you don't know. --NEVER give your name or other personal information to anyone online. --If you must post a picture online, post one that doesn't have anything that would identify your where you live. And no inappropriate pictures. --If someone you don't know tries to instant-message you online, asks for personal information, or asks for inappropriate pictures/actions, tell a parent or trusted adult. --Some ISPs have separate sites for children (Yahoo/Yahooligans) or a separate setting (AOL). Take advantage of them. --If someone wants to take inappropriate pictures/webcam shots of you, refuse and immediately call the adults.
