All those fond of spying on their spouse's phones may need to have a re-think.

Before you go berserk, it is not applicable in Nigeria yet, but you never can tell what tomorrow will be like, especially when people now kill their spouse after reading some suspicious messages in their mobile phone. 

Spying on your spouse’s phone in Saudi Arabia now carries a $133,000 fine and up to a year in prison, under a new law that aims to “protect morals of individuals and society and protect privacy’’.

The punishment would apply to both men and women in the ultra-conservative Muslim kingdom, according to a statement on Tuesday by the ministry of culture.

It could tend to protect husbands from their wives.

As in many other parts of the Muslim world, Saudi laws on divorce, inspired by scripture, often required wives seeking alimony to provide evidence of abuse or sexual promiscuity.

A husband’s phone could be a rich source of such evidence.

The Anti-Cybercrime Law, says, "spying on, interception or reception of data transmitted through an information network or a computer without legitimate authorisation” is a crime.

It imposes a penalty up to $133,000, prison or both.

“Social media has resulted in a steady increase in cybercrimes such as blackmail, embezzlement, and defamation, not to mention hacking of accounts’’, the ministry said.
