Diss drive: Seagate and IBM bring blockchain sledgehammer to compliance nuts

Electronic fingerprints put in verifiable ledger


Seagate and IBM are using IBM's blockchain tech to verify a disk drive's authenticity using its electronic fingerprint.

The blockchain drive, er, drive is apparently a way for the firm to deal with the problem of fake or counterfeit HDDs. These may be sold online and are typically relabelled old drive units with apparently higher capacities and speeds. Because they are older drives, their lifetime will be shorter than new drives as well as having lower than labelled capacity and/or speed.

The idea is that Seagate furnishes an electronic ID (eID) at the time of manufacture and registers this, with product authentication data, on IBM's blockchain platform in its public cloud. The blockchain platform is powered by the Linux Foundation's Hyperledger Fabric distributed ledger framework.

This blockchained eID can be updated during the drive's life, with, for example, a digital certificate of data purge, electronically signed by the device under a Seagate Secure public key infrastructure (PKI). This would be stored on the blockchain for compliance management with emerging global data privacy laws.

We're told the blockchained eID provides an immutable record of disk drive events. It means that, if a drive is offered for sale, its provenance could be authenticated so that you know if the 14TB 7,200rpm EXOS drive is for real and not a cheap old relabelled 8TB 5,400rpm drive.

Seagate eID and IBM blockchain scheme

The theory sounds good but the practice in the real world will depend upon the cost and practicality of access. You would need drive details from the seller in order to check them on the IBM blockchain platform, and the seller might not be forthcoming, especially with online sales.

Big Blue and Seagate quoted an International Anti-Counterfeiting Coalition statistic, saying the global trade in counterfeit and pirated electronic products has reached more than $1.7 trillion in value. We are not told what proportion of that is disk drives, and suspect it is somewhat on the low side.

Counterfeit drives are no doubt sold but we can't really see this somewhat convoluted scheme stopping that from happening. The compliance date erase checking might be useful where you absolutely need verification, but how often is that going to happen?

Basically, buy drives from authorised resellers or the original manufacturer to avoid being caught out. ®

    Windows giant carries a PyTorch for chip designer and its rival Nvidia

    Microsoft Build Microsoft Azure on Thursday revealed it will use AMD's top-tier MI200 Instinct GPUs to perform “large-scale” AI training in the cloud.

    “Azure will be the first public cloud to deploy clusters of AMD's flagship MI200 GPUs for large-scale AI training,” Microsoft CTO Kevin Scott said during the company’s Build conference this week. “We've already started testing these clusters using some of our own AI workloads with great performance.”

    AMD launched its MI200-series GPUs at its Accelerated Datacenter event last fall. The GPUs are based on AMD’s CDNA2 architecture and pack 58 billion transistors and up to 128GB of high-bandwidth memory into a dual-die package.

    New York City this week ripped out its last municipally-owned payphones from Times Square to make room for Wi-Fi kiosks from city infrastructure project LinkNYC.

    "NYC's last free-standing payphones were removed today; they'll be replaced with a Link, boosting accessibility and connectivity across the city," LinkNYC said via Twitter.

    Manhattan Borough President Mark Levine said, "Truly the end of an era but also, hopefully, the start of a new one with more equity in technology access!"

  • Cheers ransomware hits VMware ESXi systems
    Now we can say extortionware has jumped the shark

    Another ransomware strain is targeting VMware ESXi servers, which have been the focus of extortionists and other miscreants in recent months.

    ESXi, a bare-metal hypervisor used by a broad range of organizations throughout the world, has become the target of such ransomware families as LockBit, Hive, and RansomEXX. The ubiquitous use of the technology, and the size of some companies that use it has made it an efficient way for crooks to infect large numbers of virtualized systems and connected devices and equipment, according to researchers with Trend Micro.

    "ESXi is widely used in enterprise settings for server virtualization," Trend Micro noted in a write-up this week. "It is therefore a popular target for ransomware attacks … Compromising ESXi servers has been a scheme used by some notorious cybercriminal groups because it is a means to swiftly spread the ransomware to many devices."

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.
