Spam on your smartphone – measures to reduce it and captcha security applications
© James Cridland
Smartphones are helpful gadgets for business people. You have all your business contact information right there with you, you can surf the Internet, write texts, read excel sheets, and you can check your emails where ever you are. But, spam presents a big problem- your PDA's data disk will reach its limit rather quickly when you download your emails but your account is overflowing of spam.
What can you do to reduce incoming junk mail?
(1) Install a mail filter
(2) Never reply to spam-mail
(3) Do not leave your mail-address on each and every site you visit. If you want to use a lot of online services that require registration or a valid email-address, it is better to create a new e-mail-address which you use solely for this purpose.
Webmasters equally fight against spammers. That's why you find a lot of captcha security applications on the Internet. You don't know what captcha is? Captcha is an acronym for "Completely Automated Public Turing Test to tell Computers and Humans Apart". I'm sure you have come across these small security images of letters and/or numbers, which you have to rewrite into a little box before registering on a website. And exactly this feature is called captcha. So don't get too annoyed the next time you have to copy a captcha text online, because it helps fight spam!
