Protect Your Privacy: Block Your Phone Number or Display A Fake Phone Number

At some point or other, we’ve all had the desire or need to make a phone call yet did not wish to reveal our phone number.  Below are three methods of phone number blocking that work and can be enacted immediately.

1. Use a caller ID blocking prefix. In many countries, you can enter a code before you dial a number and your phone number will be blocked from appearing on the recipient’s caller ID. The code varies depending on your country and your service provider, and it is not possible to block in all countries. Enter the prefix, followed immediately by the number you are dialing. For example, if you are in the US and want to call (555)123-4567, you would enter *675551234567.

  • North America – *67 or #31#
  • Albania, Australia, Denmark, Greece, Israel, Italy, Netherlands, Sweden, Norway: #31#
  • Argentina, Iceland, Switzerland, South Africa: *31*
  • Germany: *31# or #31#
  • Hong Kong: 133
  • Japan: 184
  • UK and Ireland: 141
  • New Zealand: 0197 (Telecom) or *67 (Vodafone)
  • Australia: 1831 or #31#
  • India: *31# – Must be enabled by network.
  • If your country is not listed, chances are you can use either *67 or #31#. Most GSM mobile networks work with #31#.

2. Contact your carrier. If you want all of your phone calls to always be blocked, you can contact your carrier and set up permanent Caller ID blocking. There is typically a charge for this, and the fees and terms will vary from carrier to carrier.

  • Most pre-paid plans cannot enable permanent Caller ID blocking.
  • Some people have Anonymous Call Rejection enabled, which means your call will not be able to be completed unless you call from an unblocked number.

3. Hide your number through your device’s settings. Many phones allow you to block your Caller ID information by changing the phone’s settings. If your phone does not have the option to do this, then it is not allowed by your carrier, and you will have to try one of the previous steps.

  • iPhone – Open the Settings app, tap Phone, tap Show My Caller ID, and then toggle the slider to ON.
  • Android 4.0 and earlier – Open the Settings app, tap Call, tap “Additional settings”, tap Caller ID, and then tap “Hide number”.
  • Android 4.1 and later – Open the Phone app, tap the Menu button, tap “Call settings”, tap Caller ID, tap “Hide number”.
  • Windows Phone 8 – Open the Phone app, tap the More button (…), tap “settings”, tap the box under “Show my caller ID to”, tap “no one” or “my contacts”.
  • BlackBerry – Press the Menu key, click Options, click General Options, find the Restrict My Identity field, set it to Always.

Fake Phone Number: If however you wish to display a fake phone number, try one of the many apps available that do just that – pop up a fake phone number on your target’s phone.  A new app on the market also allows you to change your voice to sound like a man or a woman: FakeCallerID.  Let’s bear in mind that ultimately, all fake phone numbers are logged somewhere and if necessary, law enforcement can certainly obtain these records.

Alexa, Can You Dial 911 While Recording My Murder? The Electronic Ear & The Law.

policeline

Unless you are living under the proverbial rock, I’m sure by now that you’ve heard of the criminal case in Arkansas which has the police subpoenaing Amazon for the cloud-maintained audio files that may have been recorder by  the alleged murderer’s IoT gadget, the personal electronic assistant known as Echo.

Case Background (as featured in Engadget):

Amazon’s Echo devices and its virtual assistant are meant to help find answers by listening for your voice commands. However, police in Arkansas want to know if one of the gadgets overheard something that can help with a murder case. According to The Information, authorities in Bentonville issued a warrant for Amazon to hand over any audio or records from an Echo belonging to James Andrew Bates. Bates is set to go to trial for first-degree murder for the death of Victor Collins next year.

Amazon declined to give police any of the information that the Echo logged on its servers, but it did hand over Bates’ account details and purchases. Police say they were able to pull data off of the speaker, but it’s unclear what info they were able to access. Due to the so-called always on nature of the connected device, the authorities are after any audio the speaker may have picked up that night. Sure, the Echo is activated by certain words, but it’s not uncommon for the IoT (Internet of Things) gadget to be alerted to listen by accident.

Police say Bates had several other smart home devices, including a water meter. That piece of tech shows that 140 gallons of water were used between 1AM and 3AM the night Collins was found dead in Bates’ hot tub. Investigators allege the water was used to wash away evidence of what happened off of the patio. The examination of the water meter and the request for stored Echo information raises a bigger question about privacy. At a time when we have any number of devices tracking and automating our habits at home, should that information be used against us in criminal cases?

Bates’ attorney argues that it shouldn’t. “You have an expectation of privacy in your home, and I have a big problem that law enforcement can use the technology that advances our quality of life against us,” defense attorney Kimberly Weber said. Of course, there’s also the question of how reliable information is from smart home devices. Accuracy can be an issue for any number of IoT gadgets. However, an audio recording would seemingly be a solid piece of evidence, if released.

Just as we saw with the quest to unlock an iPhone in the San Bernardino case, it will be interesting to see how authorities and the companies who make smart home devices work out the tension between serving customers, maintaining privacy and pursuing justice.

Update: An Amazon spokesperson gave Engadget the following statement on the matter:

“Amazon will not release customer information without a valid and binding legal demand properly served on us. Amazon objects to overbroad or otherwise inappropriate demands as a matter of course.”

As a refresher, Echo only captures audio and streams it to the cloud when the device hears the wake word “Alexa.” A ring on the top of the device turns blue to give a visual indication that audio is being recorded. Those clips, or “utterances” as the company calls them, are stored in the cloud until a customer deletes them either individually or all at once. When that’s done, the “utterances” are permanently deleted. What’s more, the microphones on an Echo device can be manually turned off at any time.

I think we will all find the ever-changing digital landscape an interesting venue for the evolution of electronic law. The ramifications of the anticipated ruling may change the way we view individual privacy forever.  If we don’t have a reasonable expectation of privacy in our own homes… where then?

We will be following this case with particular interest and will bring you updates as developments occur.

Until this case resolves, and if you own a digital personal assistant,  you might want to drop that habit of talking to yourself.  The walls literally have (electronic) ears.
