California Appeals Court Urged to Allow Defense Review of DNA Matching Software

If a computer DNA matching program gives test results that implicate you in a crime, how do you know that the match is correct and not the result of a software bug? The Electronic Frontier Foundation (EFF) has urged a California appeals court to allow criminal defendants to review and evaluate the source code of forensic software programs used by the prosecution, in order to ensure that none of the wrong people end up behind bars, or worse, on death row.

In this case, a defendant was linked to a series of rapes by a DNA matching software program called TrueAllele. The defendant wants to examine how TrueAllele takes in a DNA sample and analyzes potential matches, as part of his challenge to the prosecution’s evidence. However, prosecutors and the manufacturers of TrueAllele’s software argue that the source code is a trade secret, and therefore should not be disclosed to anyone.

“Errors and bugs in DNA matching software are a known problem,” said EFF Staff Attorney Stephanie Lacambra. “At least two other programs have been found to have serious errors that could lead to false convictions. Additionally, different products used by different police departments can provide drastically different results. If you want to make sure the right person is imprisoned—and not running free while someone innocent is convicted—we can’t have software programs’ source code hidden away from stringent examination.”

The public has an overriding interest in ensuring the fair administration of justice, which favors public disclosure of evidence. However, in certain cases where public disclosure could be too financially damaging, the court could use a simple protective order so that only the defendant’s attorneys and experts are able to review the code. But even this level of secrecy should be the exception and not the rule.

“Software errors are extremely common across all kinds of products,” said EFF Staff Attorney Kit Walsh. “We can’t have someone’s legal fate determined by a black box, with no opportunity to see if it’s working correctly.”

Lawsuit on Behalf of 11 Travelers Challenges Unconstitutional Searches of Electronic Devices

Boston, Massachusetts—The Electronic Frontier Foundation (EFF) and the American Civil Liberties Union (ACLU) sued the Department of Homeland Security (DHS) today on behalf of 11 travelers whose smartphones and laptops were searched without warrants at the U.S. border.

The plaintiffs in the case are 10 U.S. citizens and one lawful permanent resident who hail from seven states and come from a variety of backgrounds. The lawsuit challenges the government’s fast-growing practice of searching travelers’ electronic devices without a warrant. It seeks to establish that the government must have a warrant based on probable cause to suspect a violation of immigration or customs laws before conducting such searches.

The plaintiffs include a military veteran, journalists, students, an artist, a NASA engineer, and a business owner. Several are Muslims or people of color. All were reentering the country from business or personal travel when border officers searched their devices. None were subsequently accused of any wrongdoing. Officers also confiscated and kept the devices of several plaintiffs for weeks or months—DHS has held one plaintiff’s device since January. EFF, ACLU, and the ACLU of Massachusetts are representing the 11 travelers.

“People now store their whole lives, including extremely sensitive personal and business matters, on their phones, tablets, and laptops, and it’s reasonable for them to carry these with them when they travel. It’s high time that the courts require the government to stop treating the border as a place where they can end-run the Constitution,” said EFF Staff Attorney Sophia Cope.

Plaintiff Diane Maye, a college professor and former U.S. Air Force officer, was detained for two hours at Miami International Airport when coming home from a vacation in Europe in June. I felt humiliated and violated. I worried that border officers would read my email messages and texts, and look at my photos,” she said. “This was my life, and a border officer held it in the palm of his hand. I joined this lawsuit because I strongly believe the government shouldn’t have the unfettered power to invade your privacy.”

Plaintiff Sidd Bikkannavar, an engineer for NASA’s Jet Propulsion Laboratory in California, was detained at the Houston airport on the way home from vacation in Chile. A U.S. Customs and Border Protection (CPB) officer demanded that he reveal the password for his phone. The officer returned the phone a half-hour later, saying that it had been searched using “algorithms.”

Another plaintiff was subjected to violence. Akram Shibly, an independent filmmaker who lives in upstate New York, was crossing the U.S.-Canada border after a social outing in the Toronto area in January when a CBP officer ordered him to hand over his phone. CBP had just searched his phone three days earlier when he was returning from a work trip in Toronto, so Shibly declined. Officers then physically restrained him, with one choking him and another holding his legs, and took his phone from his pocket. They kept the phone, which was already unlocked, for over an hour before giving it back.

“I joined this lawsuit so other people don’t have to have to go through what happened to me,” Shibly said. “Border agents should not be able to coerce people into providing access to their phones, physically or otherwise.”

The number of electronic device searches at the border began increasing in 2016 and has grown even more under the Trump administration. CBP officers conducted nearly 15,000 electronic device searches in the first half of fiscal year 2017, putting CBP on track to conduct more than three times the number of searches than in fiscal year 2015 (8,503) and some 50 percent more than in fiscal year 2016 (19,033). 

“The government cannot use the border as a dragnet to search through our private data,” said ACLU attorney Esha Bhandari. “Our electronic devices contain massive amounts of information that can paint a detailed picture of our personal lives, including emails, texts, contact lists, photos, work documents, and medical or financial records. The Fourth Amendment requires that the government get a warrant before it can search the contents of smartphones and laptops at the border.”

Below is a full list of the plaintiffs:

 ·      Ghassan and Nadia Alasaad are a married couple who live in Massachusetts, where he is a limousine driver and she is a nursing student.

 ·      Suhaib Allababidi, who lives in Texas, owns and operates a business that sells security technology, including to federal government clients.

 ·      Sidd Bikkannavar is an optical engineer for NASA’s Jet Propulsion Laboratory in California.

 ·      Jeremy Dupin is a journalist living in Boston.

 ·      Aaron Gach is an artist living in California.

 ·      Isma’il Kushkush is a journalist living in Virginia.

 ·      Diane Maye is a college professor and former captain in the U. S. Air Force living in Florida.

·      Zainab Merchant, from Florida, is a writer and a graduate student at Harvard University.

·      Akram Shibly is a filmmaker living in New York.

·      Matthew Wright is a computer programmer in Colorado.

The case, Alasaad v. Duke, was filed in the U.S. District Court for the District of Massachusetts.
