When you register to some websites,they ask you mail id for registration.These website services often promise not to sell your email id and maintain privacy.If you feel insecure of this then you have to use a + sign to your Gmail id while registering.
If you are going to register at some site called as Sample.com and feel insecure to provide your mail id then you can use Yourname+something@gmail.com .When Gmail sees a “+” in an email address, it uses all the characters to the left of the plus sign ,ie. Yourname@gmail.comGo to Settings, set up a filter.
In the From box, add Sample site.In the To box, put in your newly-created Yourname+something@gmail.com address, and set the filter to put in a folder named as “Something”.Now all their spammy mails will go directly to the trash.
Share your experiences in the comments.

Emails can resurface after deletion
-
Washington: Beware, emails or Facebook posts or pictures can resurface months after they are deleted - in the wrong hands or at the wrong time, according to researchers.
"If you care about privacy, the Internet today is a very scary place," said University of Washington (UW) computer scientist Tadayoshi Kohno. "If people understood the implications of where and how their email is stored, they might be more careful or not use it as often."
For instance, a lost cell phone can expose personal photos or text messages. A legal investigation can subpoena the entire contents of a home or work computer, uncovering incriminating, inconvenient or just embarrassing details from the past.
The team of UW computer scientists developed a prototype system called Vanish that can place a time limit on text uploaded to any web service through a web browser. After a set time text written using Vanish will, in essence, self-destruct.
Study co-authors include Roxana Geambasu, Tadayoshi Kohno, Hank Levy and Amit Levy, all with UW's department of computer science and engineering.
"When you send out a sensitive email to a few friends you have no idea where that email is going to end up," Geambasu said.
"For instance, your friend could lose her laptop or cell phone, her data could be exposed by a hacker, or a subpoena could require your e-mail service to reveal your messages. If you want to ensure that your message never gets out, how do you do that?"
Many people believe that pressing the "delete" button will make their data go away. "The reality is that many web services archive data indefinitely, well after you've pressed delete," Geambasu said.
Simply encrypting the data can be risky in the long term, the researchers say. The data can be exposed years later, for example, by legal actions that force an individual or company to reveal the encryption key.
"In today's world, private information is scattered all over the Internet, and we can't control the lifetime of that data," said Levy.
"And as we transition to a future based on cloud computing, where enormous, anonymous data centres run the vast majority of our applications and store nearly all of our data, we will lose even more control."
Researchers compare using Vanish to writing a message in the sand at low tide, where it can be read for only a few hours before the tide comes in and permanently washes it away.
Erasing the data doesn't require any special action by the sender, the recipient or any third party service.
A paper about the project went public on Tuesday and will be presented at the Usenix Security Symposium Aug 10-14 in Montreal, Canada.

A character from 'Cars', an animated film by Pixar.
New York: Talking cars aren't science fiction anymore - thanks to scientists who have developed a set of algorithms that will allow robotic cars of the future to communicate with each other to help avoid collisions.
An international team, led by Indian-origin scientists Dr Bhibhya Sharma and Dr Utesh Chand of the University of the South Pacific, has developed the mathematical equations which would also instruct robotic cars how to change lanes safely.
According to Dr Sharma, the series of mathematical equations would instruct robotic cars when and how to merge lanes, which could lead to less accidents and ease traffic congestions. "Flocking is a biologically inspired technique and a strategy commonly used in robotics. One of the advantages of flocking is that robots can work together and achieve what would take individuals far longer," he said.
In fact, according to the scientists, each car will be controlled by a centralised brain guided by a series of algorithms. The brains will talk to each other and instruct the cars to merge lanes and move in formation together.
The team demonstrated the technique using computer simulation and is currently trialling it in two wheel robots.
