The Federal Trade Commission has proposed stricter online privacy guidelines for children under the age of 13.

The FTC's proposal would clarify that an advertising network or plug-ins and certain smartphone apps must have parental consent before data can be collected about children 12 and under.

For example, the proposed rules would make it clear that an app or ad network which gathers a person's location would not be available for a young child without parental consent.

The new rules could go into effect sometime next month.
