Are you scared of being caught by your ISP or any other third party user while having a personal search about your required private data . Google has made a good incremented by providing Secure Socket Layer over their search engine’s protocol.
Now search your required information by just changing the protocol from http:// to https://. Now you have to type https://google.com on your addressbar rather then the traditional http://google.com, and your required query and your search data will by encrypted through Secure Socket Layer (SSL).
Whats SSL ?
SSL (Secure Sockets Layer) is a protocol that helps provide secure Internet communications for services like web browsing, e-mail, instant messaging, and other data transfers. When you search over SSL, your search queries and search traffic are encrypted so they can’t be read by any intermediary party such as employers and internet service providers (ISPs).
Why SSL ?
SSL encrypts the communication channel between Google and a searcher’s computer. When search traffic is encrypted, it can’t be read by third parties trying to access the connection between a searcher’s computer and Google’s servers.
Caution :
Your Google experience using SSL search might be slighly slower than you’re used to because your computer needs to first establish a secure connection with Google. – From Google explanation of SSL Search
