Hashing Videos and Images Explained
March 17, 2019
A quite lucid explanation of video and image identification appears in “How Hashing Could Stop Violent Videos from Spreading.” Here’s one passage from the article:
Video hashing works by breaking down a video into key frames and giving each a unique alphanumerical signature, or hash. That hash is collected into a central database, where every video or photo that is uploaded to a platform is then compared against that dataset. The system requires a database of images and doesn’t use artificial intelligence to identify what is in an image — it only identifies a match between images and videos.
CNN emphasizes Microsoft’s PhotoDNA technology. Information about that system may be found at this link. The write up points out that Facebook and Google use “this technology.”
One question is, “If the technology is available and in use, why are offensive videos and images finding their way into public facing, easily accessible systems?”
The answer according to an expert quoted in the CNN story is:
The decision not to do this [implement more effective hashing filter methods] is a question of will and policy—not a question of technology.”
The answer is that platforms are one way to avoid the editorial responsibility associated with old school methods of communication; for example, wire services, newspapers, and magazine. These types of communication were not perfect, but in many cases, an editorial process prevented certain types of information from appearing in certain publications. So far, the hands off approach of some digital channels and the over hyped use of smart software have not been as effective as the hopelessly old fashioned processes used by some traditional media outlets.
So will? Policy?
Nah, money, expediency, and the high school science club approach to management.

GPS: Ubiquitous and Helpful in Surprising Ways
March 6, 2019
Here’s a little write-up that highlights the power of GPS and WiFi tracking. Digital Trends reports, “It Turns Out That Find My iPhone Is Really Good at Finding a Stolen Car, Too.” Writer Andy Boxall relates:
“After stopping at an intersection, Chase Richardson was carjacked by an armed man who shouted for him to get out of the vehicle. Sensibly complying, Richardson got out, but at the same time left his work-issued Apple iPhone in the car. The criminal also demanded Richardson’s wallet and his own personal phone, then got in the car and drove away. The police arrived after Richardson called 911 at a Walgreens store, which is when the Find My iPhone feature was called into action. The service uses GPS to generally locate a registered device, which in this case was the work phone. The police apparently used Find My iPhone in real time to track down the stolen car. A police helicopter was called in to assist after the car was located, as the thief tried to evade arrest.”
We are pleased to learn Mr. Richardson was not hurt during the carjacking. Boxall mentions other cases where Find My iPhone has led to arrests, and notes similar tools like Google’s Find My Device, Samsung’s device location service, and third-party companies like Cerberus Anti-Theft. Such tools can be a huge help if someone makes off with your phone—or your car. Just remember that tracking software can have unintended consequences; the article closes with this kind wish:
“Whichever you choose, we hope it will only ever be used to find your phone down the back of a couch, and nothing more serious.”
We agree.

Moving the Google: Right to Be Forgotten Has an Impact
January 23, 2019
I have heard that it can be difficult to reach a human at Google. It appears that a Dutch surgeon and her attorneys were successful. “Right to Be Forgotten Used to Force Google to Remove Medical Negligence Link” states:
Amsterdam’s district court has forced Google to remove search results relating to a Dutch surgeon’s past medical suspension…
The difference between printed information and digital information is becoming discernible. Print can exist in multiple copies in tangible form in many places; for example, university libraries, archives, and personal information collections. Making a change to a printed document can be tricky, but it can be done.
However, changing the digital record is a bit easier; for example, deleting a pointer in an index.
The question becomes, “What happens when a person wants to reconstruct the details of a particular matter?”
The answer is that information is relative. Figuring out what happened becomes a bit more difficult and expensive.
What happens?
I can’t look up the answer online, but I could ask IBM Watson. These types of answers may have to suffice with Silly Putty information.
A court decision may leave behind a paper trail. But the actions of a single system administrator may be impossible to identify and verify.
Epistemology may be due for a renascence when setting the record straight.

About Those VPNs
December 26, 2018
News and chatter about VPNs are plentiful. We noted a flurry of stories about Chinese ownership of VPNs. We receive incredible deals for VPNs which are almost too good to be true. We noted this write up from AT&T (a former Baby Bell) and its Alienvault unit: “The Dangers of Free VPNs.”
The idea behind a VPN is hiding traffic from those able to gain access to that traffic. But there is a VPN provider in the mix. From that classic man in the middle position, the VPN may not be as secure as the user thinks.
The AT&T Alienvault viewpoint is slightly different: VPNs are the cat’s pajamas as long as the VPN is AT&T’s.
We learned from the write up:
Technically, VPN providers have the capacity to see everything you do while connected. If it really wanted to, a VPN company could see what videos you watched, read emails you send, or monitor your search history.
The write up points out without reference to lawful intercept orders, national security letters, and the ho hum everyday work in cheerful Ashburn, Virginia:
Thankfully, reputable providers don’t do this. A good provider shouldn’t take any logs of your activity, which means that although they could theoretically access your data, they discard it instead. These “no-log” companies don’t keep copies of your data, so even if they get subpoenaed by a government agency, they have no data that they can hand over. VPN providers may take different types of logs, so you need to be careful when reading the fine print of any potential provider. These logs can include your traffic, DNS requests, timestamps, bandwidth and IP address.
The write up includes a “How do I love thee” approach to the dangers of free VPNs.
Net net: Be scared. Just navigate to this link. AT&T provides VPN service with the goodness one expects.
By the way, note the reference to “logs.” Many gizmos in a data center offering VPN services maintain logs. Processing these auto generated files can yield quite useful information. Perhaps that’s why there are free and low cost services.
Zero logs strikes Beyond Search as something that is easy to say but undesirable and possibly difficult to achieve.
Are VPNs secure? Is Tor?
In January 2019, Beyond Search will cover more dark cyber related content. More news is forthcoming. Let’s face it enterprise search is a done deal. The Beyond Search goose is migrating to search related content plus adjacent issues like AT&T promoting its cheerful, unmonitored, we’re really great approach to online.

Deep Fakes: Technology Is Usually Neutral
December 18, 2018
Ferreting out fake news has become an obsession for search and AI jockeys around the globe. However, those jobs are nothing compared to the wave of fake photos and videos that grow increasingly convincing as technology helps to iron out the wrinkles. That’s a scary prospect to more than a few experts, as we discovered in a recent MIT Technology Review article, “Deepfake Busting Apps Can Spot Even A Single Pixel Out of Place.”
According to the story:
“That same technology is creating a growing class of footage and photos, called “deepfakes,” that have the potential to undermine truth, confuse viewers, and sow discord at a much larger scale than we’ve already seen with text-based fake news.”
Deepfakes are fun and possibly threatening to some. The “experts” at high tech firms will use their management expertise to reduce any anxieties the deepfakes spark. But some Luddites think these videos and images have the potential to disrupt governments and elections in countries where online is pervasive. Beyond Search is comforted by the knowledge that bright, objective, ethical minds are on the case. One question: What if these whiz kids are angling for a more selfish outcome?

Quote to Note: Experts from UK Take a Look at US Social Media
December 17, 2018
I read “Silicon Valley’s ‘Belated and Uncoordinated’ Efforts at Dealing with Russian Fake News Revealed.” The report was created by experts in the UK and leaded to the Washington Post.
Here’s a quote which suggests the principal finding:
“Social media have gone from being the natural infrastructure for sharing collective grievances and coordinating civic engagement to being a computational tool for social control, manipulated by canny political consultants and available to politicians in democracies and dictatorships alike,” the authors of the report wrote.
The idea is that technology is neutral until a person figures out how to use it as a weapon or to his or her advantage.
In the case of social media, the companies managed as if they were high school science clubs’ entries in a Science Fair, have created some interesting tools. A few of the tools are similar to the wizard who creates a death ray, uses it to cook a burger, and gives the gizmo away at a yard sale. A clever person picks it up and starts vaporizing the pets and the neighbors.
Remember that technology is neutral mantra. That’s something repeated by individuals who have not read The Technological Bluff by Jacques Ellul.
Does one want to access “all the world’s information”? Not me. Selectivity, editorial controls, policy controls, and informed decision making are helpful.
Anyone remember that Pandora’s box thing? In January 2019, Beyond Search is switching focus, and we are introducing a Web log to complement our video series “DarkCyber.”
Times, they are a-changin’.
