With no federal data privacy law on the books, states are doubling down on new laws governing the protection of people’s data.

In the past year, Delaware, Indiana, Iowa, Montana, Oregon, Tennessee and Texas have all enacted such laws, more than doubling the number states had them previously — those being California, Colorado, Connecticut, Utah and Virginia.

Although that represents progress, it’s also a challenge for companies doing business nationally to keep track of the subtle differences among the various laws. My analysis for SiliconANGLE here.
