Elke dag moeten providers een deel van hun klantenadministratie uploaden naar een centrale database. We moeten erop vertrouwen dat de overheid daar dan netjes mee omgaat. Maar de jaarlijkse audits laten zien dat de minister nog altijd weinig op heeft met jouw privacy.
Zou een crimineel ermee wegkomen als hij zegt zich steeds beter aan de wet te houden? Waarom de minister dan wel?
Another critical look on the blockchain and Bitcoin:
Each purported use case — from payments to legal documents, from escrow to voting systems—amounts to a set of contortions to add a distributed, encrypted, anonymous ledger where none was needed. What if there isn’t actually any use for a distributed ledger at all? What if, ten years after it was invented, the reason nobody has adopted a distributed ledger at scale is because nobody wants it?
I’ve been skeptical for a while now about how everything seems to be solved by “blockchain”. Bozhidar Bozhanov seems to share many of my thoughts and wrote them up already:
I can’t see why it would be useful to abandon a centralized database that you can query in dozens of ways, test easily and scale trivially in favour of a clunky write-only, low-throughput, hard-to-debug privacy nightmare that is any public blockchain.
I can see how a pseudo-public blockchain can, for instance, be useful as a clearing-house mechanism between banks, but for now I’ll stick with a regular bank myself. They’re not perfect, but I think the time society has spent on regulating banks, and the service banks provide here in The Netherlands and Europe, still give me a lot more ease of use and peace of mind than the yahoo libertarianism of many blockchain advocates.
Do new technologies and methods render the dimensional model obsolete? The top question from readers of this blog continues to be: “Is the dimensional model still relevant?” It is easy to understand why people ask this question: Our BI programs have expanded beyond data warehousing to include performance management, analytics, and governance functions.
As we move to treat information as a business asset, the dimensional model has become a critical success factor.
There are these stories about how long it took for radio, tv, the internet to reach a certain influence on society (less and less, some would like to extrapolate that to the Singularity). There also should be stories about how long it took for each technology to reach corporate dominance over that technology, preventing it to serve social justice and progress…
Many Software-as-a-Service companies from abroad are currently setting up European data centers, often together with European partners. With this, they hope to ease the growing European concerns around privacy, data protection and complying with existing and upcoming regulations like the EU General Data Protection Regulation (GDPR). But recent developments in US courts show this to be a risky proposition: the problem of privacy is far from resolved by ‘just’ putting data in Europe. For companies betting on Privacy Shield, using services from US companies directly or through an intermediary storing data in Europe, all this is very bad news.
My reservation with block chains and crypto currencies: they disempower the ordinary person (or user)… instead of the Bad Guy On The Corner taking your wallet, now anyone anywhere can steal all your money, and you might not even notice it at first.
The press is reporting a $32M theft of the cryptocurrency Ethereum. Like all such thefts, they’re not a result of a cryptographic failure in the currencies, but instead a software vulnerability in the software surrounding the currency — in this case, digital wallets.
This is my concern about digital cash. The cryptography can be bulletproof, but the computer security will always be an issue.
