Abstract: A computing system receives a request to verify a user, the request comprising an indication of a jurisdiction in which the user will be verified. Based on the request, the computing system collects information related to the user. Based on the request, the computing system identifies a workflow corresponding to the jurisdiction. The workflow defines conditions for obtaining a verified status in the jurisdiction. The computing system executes the workflow to verify the user. The computing system hashes the verification record using a zero-knowledge proof protocol. The computing system generates a non-fungible token corresponding to the verification record. The non-fungible token is associated with a hashed version of the verification record. The computing system broadcasts the non-fungible token to a blockchain.

Abstract: A method for manufacturing a semiconductor device includes: providing a wafer-bonding stack structure having a sidewall layer and an exposed first component layer; forming a photoresist layer on the first component layer; performing an edge trimming process to at least remove the sidewall layer; and removing the photoresist layer. In this way, contaminant particles generated from the blade during the edge trimming process may fall on the photoresist layer but not fall on the first component layer, so as to protect the first component layer from being contaminated.

Abstract: An image capture system includes a first image capture device, a second image capture device and a processing device, and the processing device is electrically connected to the first image capture device and the second image capture device. The first image capture device is configured to capture a first image, and the second image capture device is configured to capture a second image.

The weights each has a spring member to bias and force the inner end of the latch rod to engage with and to latch the weights to the bar. The weights each includes a panel having an orifice to slidably receive the latch rod, and to anchor the latch rod to the panel when the catch of the knob is rotated relative to the panel.

Abstract: A weight lifting device includes a handle having two end segments, a number of weight members each having a slot to receive either of the end segments of the handle, and an anchor plate rotatably attached to each of the weight members and having an opening selectively aligned with the slot of the weight member, to selectively receive either of the end segments of the handle. The anchor plate is rotatable relative to the weight member to offset the opening of the anchor plate from the slot of the weight member, and to selectively anchor the weight member to the handle. The desired number of weight members may thus be selectively attached to the handle.
